I haven't bet on sports in a long time. I now much prefer casino games like slots, which don't have a win percentage, so we can't gauge how much we'll win if our predictions are correct. Essentially, if you stop when you're winning, that's your win amount.
But I don't really care about the outcome; I prefer the process, whether it's a pleasant or unpleasant experience. It really gets my adrenaline pumping and trains my self-control.
For casino games, we don't really need to measure the odds of winning. What we can feel is playing and enjoying the game. Let luck come, and we can have fun. But for sports betting, of course, there are many bettors who calculate the odds of winning rather than relying on luck.
Although some bettors certainly just bet randomly or only follow their friends' bets. They consider the odds because they have an understanding of what they are betting on. If they do not have that understanding, I think the bet would be the same as in a casino game.
