Gruber was actually at the meeting. So it would be quite hard for him to get it 'wrong'.

Phil Schiller:
... Third on the list is Mac Pro. Now, Mac Pro is actually a small percentage of our CPUs — just a single digit percent. However, we don’t look at it that way.
The way we look at it is that there is an ecosystem here that is related. So there might be a single digit percentage of pros who use a Mac Pro; there’s that 15 percent base that use Pro software frequently, and 30 percent who use it casually, and that these are related. These are not distinct little silos. There’s a connection between all of this.

Phil Schiller was chief of marketing for Apple. So the notion that he doesn't know what the sales numbers accurately are is pretty close to zero. That is one of the principle jobs of doing Marketing: figuring out the size and scope of target markets and how well your products match up to those groups.
Lots of folks hand wave and infer than Single digit percent has to be some average between 1 and 10. That's is highly likely not true. 0.5% rounded up to 1% is 'single digit percent. Which is pretty much closer to the truth. Even back in the peak days of 2008-2009 timeframe Mac Pros were south of 250,000/yr run rate. In the 2013 and on era probably lower than 100K. ( once the iMac transition from mobile to desktop processors, it dropped among other factors over the last decade or so. )
iMac unit shipments are an order of magnitude bigger than the Mac Pro. It is a hobby product for Apple. One of the main reasons why the iMac Pro was such a much priority product for Apple in 2016-2017 than the Mac Pro ( which took two years after this meeting to ship. )
Why around 1% isn't "hand waving" ? Because there are public reports about who and how big the marketshare was for workstations. For example. 2010.
"..., Jon Peddie Research senior analyst Alex Herrera reports the industry shipped 903,700 workstations, a 6.4% sequential gain from the previous quarter.
...
HP and Dell spent several previous quarters jostling for market leadership, each taking a turn with slim volume leads, with neither seizing a sustainable advantage over the other. HP, which just five years ago trailed Dell by nearly 12 percentage points, had steadily closed the gap and over the last two quarters again managed to edge out its rival.
But this time, HP’s surge appears more vigorous, with the company in Q4 taking four points more volume share than the former number one (41.3% and 37.2% , respectively).

Jon Peddie Research analyst Alex Herrera says HP has retaken the lead among workstation vendors. The workstation market continues to recover from recessionary lows, setting a record for units shipped during the fourth quarter of 2010. Completing analysis of the workstation and professional...

Dell and HP had
78% of the market. Lenovo/IBM was the historical large third place finisher. Apple was firmly in the "others" category. Apple's overall PC market share of 5% applied to that 900K/quarter run rate is about 45K per quarter. So a 4 quarters of that is around 180K. It is doubtful that Apple even had 5% in this market subsegment, so that is a high unit estimate. ( more expensive than average GPU cards. relatively limited drivers , etc. Plus the huge skew of folks buying with explicit, active support contracts(i.e., why HP/Dell/Lenovo so much better than mainstream marketshare averages ) )
Get to the 2013 and 2019 era probably not cracking 100K because either not "container expansion" or "priced thousands higher than a average workstation". ( average workstation being something like a mid-range HP/Dell. Z4 / 5000 not Z8 / 7000 ) .
P.S. The Peddie website appears to have pulled down their old archive of press release summaries about the numbers so I pulled some quotes from articles covering their press releases. And no, I didn't cherry pick some low 2010 one either.
" ... Q1’11 is now in the books, with the quarter seeing 860.0 thousand workstations shipped worldwide, representing a 4.8% sequential decline and an 18.6% year-over-year gain. Both of those figures need to be weighed in context ..."

900K/quarter is a quite healthy historical quarter.
If go back to the era where the Mini has a super low end mobile processor the Mac Pro used to outsell it. But since around 2014 (and the mini getting a very healthy "mac web services" role ) the Mini sells at much higher rates than the Mac Pro does. 2019 pricing only skewed that even higher. Very decent chance that Mac Pro's share percentage is being rounded up to get to 'single digit'. (and that is one contributing reason why Apple has a "low volume" tax on it to make it interesting enough for them to pursue as a product. ).
The M1 Mini having the same performance as the M1 iMac 24" has probably helped Mini sales. Apple's high tolerance for fratricide between the iMacs and the "headless" desktops appears to be higher since either way it is more M-series sales of the exact same silicon die (and RAM and NAND storage ) and it is a relatively cheaper display component at this point. ( not so sure they will have same tolerance for. mini-LED 27" iMac panels where they need to drive the unit sales up to get the costs down. )
