Does Everyone Suck?

I recently reached level 10 after about 729 games. I’ve won 523. I don’t have any special players, and my highest rated player currently in my starting lineup is a level 6 infiltrator. All other players are level 4/5. I run a 4-4-2 and just spam long balls into the corner with my producers. Nothing too crazy.

Yet I see all these people I play who have thousands upon thousands of games played with a win record of like 47%. Does everyone just stink at this game?
