Actually you are right that's it's a good step he toke to come and warn other gamblers that aren't yet to become addicted to gamble. However, it's not easy to get rid of gambling addictions because it's very terrible and at the beginning when you were becoming addicted to gamble gradually you will not know that you are getting addicted to gamble, and even though someone is trying to advise you based on your addictions you won't listen. So the warning is simple and gamblers should try and gamble responsibly.
But for now it's just a suggestion that sometimes even though it's very good, it can't help much. The advice we make sometimes for some people including gamblers will be considered as a breeze because in the end, advice like this will feel more useful if in the end the gambler has experienced the risks and worst possibilities that exist in gambling.
Maybe this also applies to me because for now I seem to still dislike those who only give advice to stop gambling without any solutions that really make me really realize that the dangers of gambling are greater than I imagine because if you see a lot of people who advise gambling (for myself personally are those who are still gambling too on several occasions) so that I still do gambling because people who advise to stop gambling are still gambling the same as I do.
It's easier to advise gamblers when they have losses they can't imagine and some other possibilities that can still happen for the worst, as long as that doesn't happen then gambling will continue.
