As a former uspta tennis pro and NTRP 5.0 I can assure you no recreational players can serve anywhere near as well as Diego.
The dude hits serves at targets every day (give or take), so of course his accuracy & percentages are going to be better than someone who plays 2, 3 or 4 times a week. That's not to be confused with a 6'3" amateur with an excellent serve who can hit 120+ sometimes, because that happens too on rare occasions, but it doesn't make said amateurs serve in any way better (just in case someone tries to throw that red herring into the mix).
I’ve done plenty of racquet demo events and recreational players all get a big surprise when the “big” servers are only around 70-90 mph. Hilarious.
Hah! Sounds like you are calling some posters out:

I think the original post was legitimate and interesting, but topics like this often get derailed.
But here's the thing...
Diego Schwartzman is MALE.
Don't say that on twitter or you'll get in all sorts of trouble!!

The Elon Musk takeover isn't yet complete.
Sorry mate, I couldn't resist.
I've been a little antagonistic (unintentionally) towards some posters of late, so I'm going to stay out of this one.
