To answer your question, well yes, there's a chance for you to earn, also in bitcoin, by playing a gambling game. I repeat, there's a CHANCE. Also with that chance, there will also be a chance for you to lose your money. Playing a gambling game is really risky although with high risks there is also high rewards. If you're aim is to earn money or rather bitcoin, then I don't think playing a gambling game is the best option. There's a lot of other ways to earn, so I suggest you explore those first. I hope you find the answer to your question.
The issue at hand is that the chance of making money in gambling is lower than the possibility of losing money and that is why it is such not a good thing to try gambling to earn money.
