Depends what game you are playing. I love playing poker and have always in the end made money from it. When you aremt playing head to head against the house you can easily make a living off it if you had to and depended on it. That's why in poker you see the same type people in the cash at all these tournaments. I do think poker is an anomaly because it's a mix between gambling and sport.
Some gambling does require skill to do so and the skills and knowledge you have can increase your chances of winning. With poker gambling, of course this gambling requires good skills and knowledge to be able to do it and to increase your chances of winning. Apart from that, it is possible that gambling that requires skill and knowledge can be done well to produce frequent wins, if by consistently producing wins with every gamble you make, it is not possible to produce a win, there are times when the poker gambling you do loses, or before we go any further we have withdrawn because we are not sure about the cards we are holding.
with other gambling such as slot gambling, this is gambling which in my opinion depends entirely on luck, but the similarity here is the point that must be paid attention to, namely self-control, gambling which requires skill or knowledge with gambling which completely relies on gambling alone involves self-control, but this may be more likely to lead to slot gambling. because there have been many cases of bad impacts that have occurred when they do not have good self-control with the slot gambling they do.
