Any worship will prevent us from doing something other evil in the future, maybe that's what is meant and captured from this video, acting as good people will help us become better later, therefore I can't comment much about this video before watching it's finished videos properly.
I think that is pretty much about the video, despite the inclination about gambling for the muslim faith and infact most other religions regarding to gambling but to keep the worship or prayers going on. I believe if you drop the prayer and followship because you are doing a particular sin it will lead you into deeper sins that coming out will be a longer process, that is what I understand in the video but on the other hand I'm thinking that is a subtle way to give approval to gambling by the muslim faith and not to judge or condemn theirselves yet.
