New Chess Board

Today I played Chess on my new chess board that I received and after losing a game I won a game, only it was a different bot since I'm not used to playing chess between my computer and an actual chess board?

But I could of lost anyway and I felt like the computer allowed me to win because of a mistake it made when it could have prevented my pawn from reaching white's side of the board which seems obvious and unlikely, but like an actual opponent computers make mistakes too?
