Those who gamble daily are addicts and don't gamble for fun. You will find them more than those you are talking about. Gambling is entertainment but when it becomes addiction the gambler himself won't be able to recognise this issue.
Very true. Gambling everyone starts as fun and when someone plays gambling they get attracted to it and at some point the gambler becomes addicted to gambling. I have seen many gamblers who started gambling only for fun and now become completely addicted to gambling, and have sold many of their assets at a loss and lost the money in gambling. So once a person becomes addicted to gambling it is very difficult to get rid of this addiction.
