Well, maybe experienced gamblers should be better at controlling their emotions and greed and thus, experienced gamblers do not mean that it will be easy to win but more about having good control and discipline. Because at least, so far there are those who assume experienced gamblers will have good skills to be able to win in gambling, but I think the reality is not so. So yes, when experienced gamblers have discipline then it will be very possible for them to be able to stop when they get a winning streak, it would be impressive of course so as not to end up losing.
experienced or beginner, when a gambler has control over himself and what he bets, then most likely he has become a good gambler. It is difficult to see a beginner gambler with good control and discipline in the game. But not all beginners play in a hurry and are ambitious to win bigger. Gamblers must know when to continue the game and when to stop the game. This is simple but certainly difficult for every gambler because more gamblers think about big wins and jackpots.
