You said it right and like what I mentioned there's some who can make it and manage to make money out from their gambling activities but the thing is, the majority will not and we do know the bad implication of gambling, when things went out of control then that gambler will sort everything to gambling and their focus is no longer to their education, but more on how they'll find ways and that best strategy that will fits them to win.
Like they say, gambling is a game of luck and chances, and luck can fall on anyone’s side at anytime, making them to maximize profit. Additionally, when you’re able to come up with a good and effective strategy, it helps you to increase your chances of winning but it is still not guaranteed. Some people even claim to be making much money from gambling, while in reality, it’s nothing but an exaggerated claim, and some people end up falling for this misinformations and end up having misconceptions about gambling, that’s when you see them chasing the wins, and rather than getting the wins, they get the losses instead, and like we already know, this could potentially lead to loss chasing too and then more losses till you’re completely drained if you’re unable to control your emotions.
