You might be able to try it yourself or you can see your own friends who do gambling types that you don't know because I'm sure in your environment there are those who do it either with slot gambling or with crash. These two games are quite popular among the community so I think you can find other people around you doing it and yes including your friends I think some do it.

I myself prefer slot type games because there are no predictions or special skills to do it we just need to wait for luck to be on our side and the spin that occurs gives victory, but this is not much different from the crash game which clearly both of these games involve luck.
