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.
If you play a game for money or bet money on something, it will be considered gambling. It does not matter how long you bet there or how much money you bet. However, if you are addicted to gambling, then as long as you enjoy gambling, you will be considered a gambler. However, when you stop gambling, you will not be considered a gambler and no one will mention you as a gambler. But if you are an addicted gambler, then everyone will always call you a gambler and mention you as a gambler. So how long you will be considered a gambler will depend on your gambling activity.
