I suppose that even if a person does not gamble for a month and then resumes gambling, they can also be called a gambler. This is possible, for example, during the off-season of some sports championships, when teams go on vacation and gamblers go on vacation in anticipation of the new season and new bets. To be called a gambler, you don't have to play slots every day and bet on any championships, any sports, or any athletes. This is no longer an indicator of a person's gambling addiction, but rather an indicator of their absolute carelessness or short-sightedness. At the same time, people often show carelessness in gambling, but it's also like financial literacy: if no one has taught you about it, then you don't really know much about it. The same applies here: if you don't know what principles to follow when gambling, you can end up in big trouble. Sometimes it's the fault of gambling, sometimes it's just plain ignorance.
