I was able to reproduce this issue with my old 13" MacBook Pro from mid-2018 by clicking near the edge of the trackpad, so I suspect it's a software setting

The reason its more noticeable on the newer 14" model is that the trackpad is smaller, so we are more than likely tapping the dead zone by accident

Never happened to me on both MB Pro 13 (2014) & MB Pro 13 (2020) with Big Sur. MB Pro 2020 has similar-sized touchpad like in MB Pro 14 (> 2020), but in MB Pro 14 it happened to me all the time.
 
Interesting - I thought the issue was solved here, but when I try to tap on the edge of the trackpad, it is still registering only the third tap. I still believe it has improved, so I try to tap in the center region of the trackpad. I can live with that.
 
The last time in a Apple Store they put in the notes: "Was able to duplicate the issue on every "m" series portable in the store. Reviewed the documentation on apple's website. I found nothing to indicate that this is unusual behavior or to indicate it should work differently. I explained that it is likely an engineering design far people who may have overlap between the keyboard and the trackpad edge when typing".
 
I returned MBP 14 because of this bug and now I'm on Intel-based MBP 2020 with Big Sur. I'm waiting for this problem to be fixed. Working with that bug for a few minutes driving me nuts (mostly open new tab in browser, text editors).
When using an external keyboard, the touchpad functions normally.
