Online Multiplayer games like Marvel Rivals

Anyone else painfully bad at online competitive games?

Theres not a single one I'm good at. I've been playing Fortnite for 7? 8? years. You would imagion I'm maybe good.

I'm not. I've practiced, done 1v1s on bots, even switched how I hold the damn controller. I couldnt improve. I feel cursed. I have the same issue with Rivals now, I cant be good.
