IWTL on how to accept being a "loser" in competitive games

I'm scared of just playing a competitive video games (I used to play Marvel Rivals and Valorant) and I enjoy the skills and abilities but I also wish they have some PvE mode that I can play on. Maybe I'm just scared of losing, intimidated by great players who can stomp on me, scared of just the pressure to win, etc.

You can say that just by playing and playing I'm gonna get used to it but what can I learn or accept mentally to just accept that there are risks of losing.

I also learned recently that what you avoid controls you so I listed down things that are related to that matter. Something like losing, competition, trashtalking, being teased.

I want to learn it since I do want to start playing sports. And maybe it will crossover to that physical sports if I ever do one. And I'm tired of being such a wuss lol
