Does anyone actually bet on tennis regularly?

Always see tennis lines pop up but never really took a deeper look. It feels unpredictable, like any player can just have a total meltdown in the middle of a set and tilt the whole match. Also, there’s so many variables - outdoor courts, indoor courts, weather, random injuries, mental stuff. My poker brain likes a bit more stability than that. But I know a couple folks who say you can find value, especially in the lesser-known matches that books aren’t watching closely.

I’m curious if anyone here actually treats tennis as a main focus or if it’s more just an occasional dabble between bigger games. Does it turn into more of a grind, following minor tournaments and hoping the numbers pan out? I’ve mostly stuck with football, basketball, and some baseball, so not sure how deep the edge goes in tennis compared to the mainline stuff. Looking to hear from anyone with experience beyond a few live bets during a Grand Slam.
