if the source of bitcoin income only from faucet I suggest don't gamble, especially if you do not have experience gambling, if you want to gamble you'll most likely lose bitcoin that you get from the faucet and it's just wasting your time
But if you get Bitcoin from faucet it's mean you get for free so if lose your Bitcoin in gambling it's still fine, will be problem is if you don't have experience and use money for your daily needs for gambling and get lose in gambling.
