first of all you need to tell your mind that gambling is very bad thing and cannot be results into profit because is totally depends upon the luck and also the cleaver games that will results only the loss of your money .
Here in my life I had never seen that any person who made much money and became rich to the gambling so here I will suggest you just forget that you can make any small amount of earning from the gambling but you can use the gambling game just for fun  purpose  .
I myself ghost much amount of money in the Bitcoin gambling so I will never suggest any one to make gambling.
