There was a kid I knew in school who I would consider a very good tetris player. One time someone else was lamenting that they always get bad pieces and he said, "The Tetris gods will never give you a piece you can't play, you just don't know how to play it." Which has resonated with me for an oddly long time in my life.

This sort of thing comes up a lot in card games like mtg. Some players are convinced they're naturally unlucky. I like to phrase it as "bad decks get bad draws". To improve one has to be luck oblivious: improve what you can, accept what you can't. Bit of a serenity prayer approach

It's also important to understand that in a best of 3 format, if you have a 80% winrate per game against every player (which is insane btw), you still lose 10% of those matches. In a 9 round tournament day (which is standard for YuGiOh iirc), your chance of winning every single round for the entire day is merely 40%. If your edge is more realistic, say 60% winrate, then you lose 35% of those matches. More games per match are your friend for determining who is actually better.
