I don't really know if similar question or concerns has been raised before, we often say that we are gamblers but does it mean that anyone who gambles once or twice is a gambler? If no, how long could someone be classified as a gambler or what games that are to be classified as someone gambling.
Drop your opinion.
I believe that a person who has played literally a couple of times in a casino cannot be called a gambler - this is just a practically random passerby in the world of gambling, and I believe that even a person who plays once every few months in an online or physical casino, or places bets - also cannot be called a gambler or a betting enthusiast, because for him it is not a hobby.
And he most likely comes in only because he gets some bonuses, and not because he is passionate about this activity and considers it a full-fledged hobby or a way to win big money.
