what kind of gambling that you think is easy to make a profit? and what strategies are you using?
First there is no guaranteed profit from gambling, that's why it's gambling, you are risking something.
Not saying you can't get profit, but it's just not guaranteed so it's never easy like you asked.
I would recommend sports betting or poker if you like those things. In those I think that you can at least make some profit if you are good enough.
If it's just luck you are searching then I like roulette and craps, although you can find games with a better house edge.
