Something that depends on luck is something that I feel cannot be associated with skill, I mean no matter how skilled we are, if we are not lucky, it will not bring any victory at all.
How many possible numbers will come out in a dice game for example? Yes, the possible numbers that come out are very many, therefore our percentage of winning is very small because it depends heavily on luck.
The fact that something is based on luck does not negate the importance of skill. I believe that most of the time, skill attracts luck. Luck, in my opinion, is the reward for effort. A gambler does not make rash decisions and hope to be lucky.
Even though there have been cases where a gambler has recorded success after making what appears to be a bad decision at first and still winning, the truth is that such events occur only 1% of the time, so gamblers should not believe that everything about gambling is based on luck and then fail to make efforts where they should.
I have seen gamblers try to study casino algorithms, and while they do not always win, they have had more success than those who do not pay attention to such things.
