People gamble for the first time in the excitement of big profits in an easy and fast way. They did not think of its bad effects and started doing it but as time went and they were badly involved and were addicted to it. They lose funds instead of making it more and are involved in some bad things. They will lose everything through this but people still love it and some make money and some lose their funds. Also some govt ūnban gambling for their people.

I am happy for you that you come to the realization and left these bad habits but remember that you can't influence others by just saying I leave it and now it's your turn to leave it, Every person has their own choice of being in it or not but yes you can provide them soem of evidence that why it is bad.
