In the short term and at the beginning, gambling can really provide big profits, that's why newbies will continue to play because they feel they can earn a lot by gambling, but in the long term gambling will bring gamblers to big losses so experience doesn't help at all. In gambling, luck plays a big role and experience only plays a very small role because experience gives the gambler the knowledge of when to stop or continue playing, not how to win the game, so without luck, experience has no influence whatsoever.
Long-term passion for gambling will not necessarily be accompanied by large losses, it seems to me that the longer a player is in gambling, the more chances he has to figure out how everything works here and start making a profit from it.
It seems to me that for a beginner the best start would be balancing at breakeven, because in case of losses at the beginning they can discourage him from trying to achieve positive results further, and just as early wins can play a cruel joke on him when he decides that he is good at gambling, and starts making big bets, then the loss will also be large. And if a player is initially in a relatively win-win balance, he will learn and gradually eliminate mistakes.
