I do not relate luck to gambling because it is so much evident that the games and odds in gambling (but odds betting) are programmed in a way that gamblers will eventually lose. Gamble more and lose is the reality. Win and do not gamble for that time wise decision. Also with the little amount of money I am using to gamble, it is like that because there is nothing like luck to me in gambling. Most people will lose while 1 out of thousands of people would win which are the lucky ones. I am not saying there is no lock in gambling but understand what I mean.
Well I guess everyone will have a personal opinion on this issue of luck being a major factor in gambling. But to be frank, luck is. it play so much role in our gambling activities than we do. When we aren't lucky our bets turns against us. But I'll agree with what you said about the loss being more than the wins of which is true. But the luck plays equal roles on each of them. What matters is that we understand that when we loss we weren't lucky for that day but when we make wins then we were..
It is never possible to win continuously from gambling, because luck will determine your win, but the truth is that luck will not be with you all the time. So even if you get small wins in the short term, in the long term such wins will never be consistent, because the casino system is designed in such a way that consistent wins will never come.
So the wisest thing to do is, If you are lucky and then have a good win, So just enjoy that win. because if you expect to win more, you are definitely going to lose it. Because you have to understand that luck will be on your side temporarily, it never guarantees long-term success.
