I agree with what @alani123 mentioned: realistically, sports betting relies heavily on luck. No matter what analysis you read or conduct, or even if you're a self-proclaimed expert, there's no accurate way to predict a match's outcome. I'm generally placing bets on football and occasionally basketball; I'm not too much of a sports person in general, and I haven't bothered with anything else.
My knowledge is pretty limited, but I've had my fair share of luck in the Euro 2024 tournament, and I've placed random bets as well. I believe we've all done it at some point; it's not that big of a deal, provided that you don't make it a habit. Sometimes you'll win, and sometimes you'll lose. As I mentioned earlier, luck is the most vital parameter. The main reason I'm not actively participating in the 2024 Olympics is because I have zero knowledge of the majority of the sports; thus, I find it too risky to go on a blind betting spree.
You shouldn't place bets blindly, no matter how much weight the luck factor has in betting. I believe that analysis and knowledge of players tip the scales in favor of the gambler. And even if the share of luck is very large, you can win if you understand sports.
Even if the chances are 45 against 55 percent - this is already a good result in the long run.
In slots, luck plays a completely decisive role, and the player's skills have no effect. That's why I don't like slots.
