The chances of losing a bet is always higher than that of winning and the mistake people make is thinking that it's vise versa. Because that's the only reason why someone will even consider the option of going all in. Another thing is greed, seeing the possibility of multiplying your bankroll in just one bet, and seeing that risk worth taking, well they should also be prepared for the disappointment that comes later because the chances of loss is there and they should know it.
That is a great truth, but I think people do it unconsciously because when they do it and they are in front of a casino, their chances of winning increase, or their thoughts grow too much towards the positive, and it may be that this thinking blinds them to reality and the reason for things, that is why we must always assume things with the true way of seeing this, games of chance, betting, we must always assume that first we will lose and second that we have to be very aware that how much money We are willing to sacrifice, it is not easy to lose money, that hurts, no one likes to lose money even if they have a lot.
