Please help me with 1's

It's just embarrassing at this point. Any tips for a struggling 1's player? I feel like I'm either way more mechanically sound than the other and I stomp them, or they somehow squeak out a win on me but either way I can't string together more than 2 wins at a time.

I feel like I'm just fundamentally missing something from 1's. Any tips for the game mode are much appreciated!
