I was talking about stress outside of gambling - in everyday real life. Gambling can help us to relax.
If you are stressed in real life, I suggest not playing gambling because you can increase your tension because of many things, whether winning or lose, that will not be good for your health. Instead of having fun and relaxing playing the games, you can spend more money because of something that can trigger your emotion to become bigger. But that is up to you 
This is what we are talking about. If everybody can gamble just for fun - we should never see the threads why the gambling so awful. But we see it every day, so the problem exists and no one solved it yet.
in fact all the problems that look terrible that we can solve are ourselves who have to think about how as gamblers to minimize all the risks that exist in gambling and cause problems to appear and look terrible. like we have to plan a money budget for gambling, control ourselves not to get emotional etc.so actually all problems and the cure of all problems for me is themselves
