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.
Indeed, gambling is undoubtedly a combination of both psychology and probability. People should always keep these two factors in check because The results are always disastrous and fatal when people allow sentiments and their emotions to overcloud their judgement when gambling, this causes some gamblers to become too optimistic about the result and outcome of the games thereby paying less attention to the presence and important of probability in gambling, this is often what makes them take certain uncalculated risks without first thinking about the potential consequences attached if the outcome of the game goes contrary to their predictions.
