It is only the cable or other plug that would have ground. That is why you need to have one, to know it ;-)

The Australia cord is grounded. I have one. See the metal rails in the slot.
the Germany plug is cord grounded. I also have one. More metal rails in the slots
The transformer with a huge grounded round metal contact.
You're also running a somewhat more dangerous combination of frequency and voltage, 230V/50Hz, so it's little wonder.
Unfortunately that also makes UK type-G plugs among the bulkiest in the world.
(Ironically, I have never seen a society more obsessed with public "health and safety" measures, while also generally having one of the more unhealthy eating and drinking habits I have yet encountered... but I digress.)
Not sure how the two are linked except in your mind. One is a set of regulations to make sure that in this case our electrical outlets and the plugs you connect to them are literally the safest in the world, while the other is a lifestyle choice. But ok.
Actually, if you take the short power connector out of the apple PSU you will notice that the notch contains contacts. If, for example, you use the extension power cable sold separately in the UK it actually connects these contacts to ground and the very noticeable buzzing that you feel disappears.
My recollection is that all MacBook Pro models I have used have given this tingly feeling unless I use this cable which sadly you have to purchase separately now.
I get that buzzing quite often, not just from the mac.
It's voltage by induction. It's the same as if you use an electrical screwdriver, with a light in it, when you touch a live wire it lights up. No circuit just induced voltage and almost no current.
Nothing to do with the earth.

Then at the least scroll to #27 or open the photos you replied to. This has been solved! The round metal guide pin is the earth! It slides in between two metal rails, also the earth.
How old is your house? If there aren't many/any grounded outlets and it's an old house, I'd also be concerned that there could be aluminum wiring. It's a definite fire hazard if so.
Its an apartment. 30 year old. No it is definately copper wires.
