If ppl don't control themself they're going to become addicted. It's sad because ppl who're controlling themself can become addicted but don't know it. I'll advise ppl to find excitement doing other things because gambling isn't good.
I wouldn't say that gambling is not a good thing. If a person realizes the risks and has good discipline, then, in this case, gambling can be just a hobby without negative consequences.
But at the same time, if a person has a strong addiction, it does not lead to anything good in any kind of activity, not only in gambling.
