It is possible that you are quite good at analyzing but there is also a possibility that previously you were nothing more than lucky, you can evaluate what you analyzed in the previous bet that led you to victory, if you find that the analysis you did really had a big contribution in achieving the previous victory then you can do the same thing on the next bet, but one thing I will suggest is to make sure that you only bet using a small amount, an amount that you can afford to lose, because of course gambling is still gambling.
You are right mate, even if he is not good in making accurate prediction, he should still not forget that gambling can always bring an uncertain result especially when you don't expect the result. He should also make sure to always use his strategy to be able to always make more accurate prediction. If he is too overconfident or cultivate the attitude of pride, he might not be able to do the predictions as accurate as before.
Yup that's the point, we are on the same page here which in my opinion gambling is still a risky activity regardless of how hard you try to predict a match to win.
So the conclusion is there is no exception to not implementing risk management such as limits on the amount of bets or expectations of winning, not infrequently I see gamblers who eventually lose control which makes them lose more money because they are too confident with predictions that they think are right and that's the reason my friend.
