The easiest way to make a profit from gambling is to not gamble. You'll profit by not losing money to this stupid addiction, saving a lot of time, and avoiding a lot of bad emotions.
yes that is the simplest answer to the question. but to me the world the most difficult and hard job is to make money from gambling. even though it is looking so easy way of earning money therefore every one is attracting by it. but i think it is one of the most difficult job of the world.
