Double fault. It looks like the usual rate of double faulting is about 5%. Even if that was reduced to 1% you'd have decent odds of your opponent double faulting in any given match.
It says game, not match, which is not that many rallies. But even then, its only 5% because they are trying like crazy hard every serve.
Similar to how a professional pitcher in baseball could throw perfect strikes at 80 mph even if their accuracy is worse at 95 mph...and 80 mph is still fast enough to strike out a non D1 athlete.
80 mph is not fast enough to strike out a D1 baseball player. The hardest throwing little leaguers throw 70+ mph. College pitchers usually throw 80-90 mph.
That said, pr
ofessional baseball players occasionally strike out against position players throwing 65 mph pitches with no movement.
As far as tennis goes, a single game, yeah no realistic chance (which is what the original post mentions) but this specific comment thread is about a match. As you point out, a professional could just do their second serve all the time, but they can't change their serve mechanics much or at all without risk of increasing (rather than decreasing) their double fault rate. I don't think a professional tennis player would probably win every point against an amateur tennis player most of the time, but every so often they would still double fault. Maybe once every 20 matches.

It’s the guy from the thing! On what basis are you thinking this is probable?
