as long as you are having the mindset that you can make money from gambling, then that means you are already getting addicted to gambling, because you going to be chasing the money always, and you will find it difficult to stop gambling even when you are suppose to stop.
It is not easy to deal with it. Mere information is of no use unless you are willing to put some real efforts. Usually gambling addicts lacks any real purpose in life because they have no skills in real world.
Addiction is associated with irrational aspect of human psyche so you can not tackle it with logic only, you need to have some sort of other passion to divert your energy and enough repetition is the key.
