If you're getting free coins from a faucet, and that site has a casino, which DOESN'T allow you to deposit ANY funds, is it considered as gambling if you use/play any of those games?
Been trying to figure out this thing for a week, but there's so much contradiction for both answers, so I am not sure how to pick "the right" answer, if there is one.
Gambling is either playing games of chance for money or taking risk. You are playing a game of chance (slot) for money (btc) and you are risking your coins you earned from a very small work therefore it is gambling.

Personally, I would still consider it as a gambling even I dont spend some coins from my wallet.
