It is sin for me, but not for you. According to everyone, the situation is different. For a person who is generally religious, gambling is a sin, for example I can say sin according to my desire.
For example, there are some religious days in our country and it is a great sin to play gambling these days. He also encourages a bigger sin if he plays in regular casinos.
yes it all depends on the individual self. If you're a religious person, if you are obedient to religion means gambling is a sin. And I think also of sin, but because human nature is diverse, there does not regard it as a sin, so that's not my problem. I always think that gambling is wrong, gambling is a sin, people have a different mind.
