I guess you meant to say a lot of gamblers, if that's what you meant, then it's through, most gamblers who are better gamblers today definitely had some kind of experience like this when they were still newbies in gambling, like myself, I was almost addicted which was as a result of misconceptions and greed. Now that I know better, the real winning in gambling is by withdrawing, not by being greedy but some people are still living with the misconception that gambling is an easy way to wealth.
Those who think gambling is an easy path to wealth certainly believe they're right, and those who try to dissuade them simply don't understand many things. However, I want to say that only the game itself can convince such players, and that lesson will be better than any teacher, and that lesson will consist of pointing out to them that they're not the luckiest people in the world, as they may have previously believed. I simply remember thinking like many players and believing that I would be the one with the best luck. Of course, it was foolish, but it's also wrong to forbid yourself from dreaming. You need to find a middle ground where you can at least think clearly and understand that losing in gambling is also a normal process.
Players who don't have much experience in the game simply hope for the best, thinking they've found a way to make money without doing anything or putting in much effort. Honestly, I'm no longer so naive, and if I see someone telling me it's easy to make money, I'm almost always convinced it's impossible, because there are subtleties we don't know. It's the same here: it's common to only talk about those who are lucky, while people prefer to keep quiet about those who lose, because there's nothing to brag about. That's why new players become overconfident, and by the second day of play, they start thinking they're smarter than everyone else.
