I think the main reason why people needs and prefer to gamble because they want an easy to get earnings, less efforts and time. In gambling people tend to satisfy their earnings from gambling even they take risk out of it.
yes and they try to play in any games and to try to be a winner in that games but the reality, sometimes they are a win and in the other times, they are lost much of money. they don't realize about this until they lost all of their money and they regret it. they feel that if they play gambling games, they can get fast money without having a job but they are wrong. gambling games cannot help us to make a fast money and only ruin our lives in the end.
