It's not really a problem if you can control it right? Being in control means that you can't go overboard or act too much when you're doing something right? So to answer your question, I don't think I do have a problem that I have days where I'm in control, I try to be disciplined as much as I can and that's why I don't have any problems, if I gamble with a set amount of bankroll, that's the only amount I will use to gamble even if the total bankroll that I have is higher than what I've set to use for that gambling session. It's difficult to do at first but once you get used to doing it, you're going to be fine, there's probably even days that you're going to quit halfway and you haven't even spent all the bankroll for that day. I try to do some self-reflection right now and recall if there's another answer to that but I can't seem to recall one, maybe the part where I get angry at close calls when I'm a streak with slots but I don't play slots too much so I don't count that part as a problem but other than that, I can't recall any, hopefully it's a good thing that I can't recall any.
If you can gamble responsibly by being able to control everything properly from money, time and actions then it is not a problem, because gambling should only be done as entertainment and should not be done excessively, because if we gamble If we overdo it, it's likely that we will have big and serious problems, and now we can see that there are many out there who gamble excessively, which makes them addicted to gambling, which is clearly detrimental to themselves.
gamble with a set budget and be disciplined with the time to gamble, where we know the limit to stop gambling, when you lose it is better to leave gambling, and when you win there is no better choice than to cash it out and go to enjoy the win. Also, most people who have problems with gambling are because of their own reckless actions in doing it, by daring to take risks but in reality they cannot accept the loss.
