Tennis isn’t pro or bust, though. There are viable career options that make tennis your life if you really want that. You could coach (whether coaching a competitive player or team, or giving lessons at a clubhouse), you could be a tennis writer, you could work adjacent to tennis like designing or selling equipment, etc.
Tangentially, I’ll add that trying and failing to become a pro gamer is very different than failing to become a streamer. At least if you’re playing competitively, you have to move beyond shit talking your opponent. There’s a lot of coordination and communication required if you’re playing a team game. Any game requires a ton of dedication and focus, and a level of creativity within the confines of the game, all of which are valuable and transferable skills. Sitting and playing games by yourself while waiting and hoping someone stops by to watch you doesn’t teach you much.
Sure, but it doesn't seem worth it to give up your childhood and early adulthood if it turns out you couldn't cut it and have to become a tennis coach instead
