It shows that making a fortune through gambling is possible if you have the skills. It’s a mistake to think we’re all destined to lose in the long run.
I guess it's not about skills. It's just that someone might get lucky, so this person is lucky. But this does not mean that anyone else is guaranteed to be lucky if they imagine that they have "skills". In general, this chain of reasoning based on one example is a characteristic "survivorship bias" when millions of losers are not taken into account. It is possible to make a fortune, but who wins depends only on chance...
When you have the skills and some luck, you’ll probably win occasionally. However, if you keep gambling, the chances of losing your winnings are high, as I’ve experienced. In gambling, you win some, you lose some. It’s important to set a goal, and once you’ve achieved it, it’s time to quit and invest your gambling profits in other ventures instead of always relying on gambling.
That is why a gambler is always advised to have the ability to stop at the right time, the first reason is because even though you have the skills but still if luck is not with you then defeat will also occur, and besides that as you said that when a gambler continues to play after winning then it is the same as you directing yourself to lose the amount of money that has previously been won (although I know the chance of getting another win is still possible), but in the end, isn't prevention always the best action? and in that situation you have managed to achieve a number of wins and isn't that what you want? Obviously, and that is why greed is always a prohibited action, none other than to avoid the possibility of losing the amount that has previously been won and also none other than to avoid yourself from significant regret. Utilizing the winnings for other potentially profitable things is also a good idea.
