I'm a tennis player and would've preferred to play as a lefty because it gives you a few advantages over most other players (i.e. ball spins differently [can catch people off-guard], a lefty's cross-court forehand [stronger shot] can be easily placed against a righty's backhand [their weaker shot]).
However, there are a number of things that I take for granted because I'm a righty (scissors, camera shutter accessible to my right hand, ink not smudging, can openers, etc) and I think I would've been frustrated as a lefty.
I noticed it helped me in both ping pong, and basketball a lot.
Ping pong just because a right isn’t use to a lefty, and a lefty is use to a righty.
Basketball in pickup games with folks who haven’t played me before, I score a lot of points as they just give me a lane to drive to the left. Then after a couple games the advantage mostly goes away.
