Hello! Hope everyone's days are going well

I've been playing ball for like 80 hours now roughly? I am really enjoying it and pretty much only play ball hahaha, I was wondering if anyone has any tips on how to get better on ball? I feel like my win percentage is quite low, being 57% (roughly) percent. I ususally die like 2-3 times in a game and get an average of 20 ish eliminations per game. Quite new to overwatch as a whole, despite the 80 ball hours hahaha, so i'm not sure if these stats are good. I am trying to learn tricks such as the wall jump technique and also figured out that i can jump off of enemy players as well. Anyway, any help would be appreciated :D Thanks!!
