Chess is a particularly poor example for your point because piece odds (the better player starting without a piece... escalating from pawn to queen) is a really good handicap system that not only makes the games more interesting but also gives each player more useful training. The better player how to play when behind and the worse player how to try to win with a material advantage. And you probably aren’t learning valuable lessons just losing to a much better player over and over again straight up. They won’t be the type of positions you’d get against players of your skill level. A much better player is likely getting decisive advantages out of the opening or early middle game, whereas especially at lower levels the middle game and endgame are much more important.
