I do not think that you will be able to earn a good income from gambling and it is also not considered as an easy way to earn Bitcoins because gambling is a more risky way to get some money. You have to try to adopt some other ways of income to earn Bitcoin. Faucet is a good way to earn bitcoin as it pay much lesser amount of Satoshi to you. It will waste a long time of you.
