Expertise and strategy are really needed in gambling so that at least we can have greater confidence compared to those who play blindly gambling, but what you say is true, because luck is the main thing needed in gambling,
Most gamblers who gamble blindly are those who already have a predisposition to addiction, Excessive activity in gambling affects a person's psychology, so they no longer promote a healthy mindset.
In any gambling game, strategy is important, especially involving experience as a skill in the game to be played.
in my opinion many of the gamblers who try various ways to be able to win the game either by sitting in certain cardinal directions and many even do mystical things just to get lucky in gambling, I think having intelligence does not necessarily win continuously if luck is not on our side.
in fact there are many people who practice things like that, by doing everything possible to get a win or luck in gambling, including people who use mysticism, whether it works or not I never know. I think this kind of behavior is no longer relevant today. The point is luck will always be the main factor in gambling.
