Honestly, its quite a rare thing to end up getting some tiny amount from the faucet and then end up with a big enough profit that you could withdraw. It is not impossible but it is as unlikely as anything could get. I would advice people to learn how to gamble, try out the demo one, and then just deposit real cash and gamble, that's the path that a newbie should take. There are too many very easy games here, not easy to make a profit but easy to understand how it works and that means you would be starting to gamble without getting into anything too complicated and could have some fun for yourself easily.
Not only quite rare, but once you do that, you are breaking the rules. Most of sites back then offers faucet for people who wanna try their site, but lot of people abused it then most of sites disabled it. I still remember people tried their luck by claimed faucet then grind it until they have reached minimum amount to tip/transfer to his other account as "bank". Then after that "bank" account already has enough minimum to WD, he just WD it. So that's one of example from Faucet abusing. Your account will get banned later once they found out you did that.
