it depends on you, which aspect you are considering to judge it right or wrong, in a general sense it is fine but when it is getting addiction for you then it should be called wrong. because addiction may destroy you.
so from my perspective, until it is not an addiction for you it's fine.
Do you think gambling and addiction are separable? 99% of gamblers are bound to get addicted because its human nature to trust your greed and block your reasoning when you see money and your hidden dreams of becoming a millionaire come true with the roll of a dice. Very few people even judge the situation and think that if it was so easy then people would not work hard to earn money. There is nothing wrong in gambling except that one had high chance of becoming an addict.
