This mentality is mainly the reason we have so many failed and unsuccessful gamblers all over the world. Those who believe in skills in winning have been successfully beating the house edge and there are numerous lists of gamblers that have done this. They might not come out to say it because they are aware a lot of people believe in luck and nothing can ever be said to change what they believe.
That will be tied to luck if you want to win in gambling, but the skills aspect will help too as in sports betting and poker, that is another factor which can lead you to win. Most people who gamble don't think or planning to be skillful because first they come to gambling place is just have fun. But then they curious more so they play more and more. Some of them learn to gamble, while others not and only depend on luck.
What if the myth to beat the casino is the knowledge of mathematics and probabilities? As you know, everyone who's in a highschool already studied how math uncovers the possibilities of winning in a game, or for something to happen. If we will try our best to rely on computation, there would be a chance that we can take advantage of most of the games that we are playing in some gambling platforms.
That could be. But do you know how many people can study math or computation better than the others? Not many, I guess. We know that people who can win in gambling are also not much, and most of them lost in gambling.
