Hello
Gambling is not a method to earn money and make profit. Gambling depends on your luck and the House always win. You can never really make a profit by gambling and hence refrain from it.
I´m sorry to inform you about your incorrectness. There is LOTS of sites where you can make a long term expected profit.
https://www.betmoose.com,
https://bitbet.us/,
http://battlecoin.org/ and all the poker sites is just a few of them.
