Sin it can only be for religious fanatics. For me, this is a great opportunity to have fun and win a good amount.
But the basics of happy life must be originating when we are believing in to something which will be having some extraordinary power. Your fun and good money may not be guaranteed all the times but those extraordinary power make a trap when you are in search of finding those. I'm not talking for religious beliefs but we need to think about why some religions are having gambling included under sin.
Nothing had happen in this world without reasons, and when we are aware of something we could make our life better than not knowing them and getting struggling for finding the root cause of it.
