Can you actually make income from playing online casino daily

Every day after my shift I log in for some roulette or blackjack. I always wonder if someone out there is actually managing to treat this as their main income, like steady enough to pay rent and groceries. I do okay here and there, but it seems like a huge stretch to rely on it. Not talking about those crazy stories where someone hits a jackpot once a year, I mean slow daily grind, playing games with a bit of edge if you can find it, or maybe just sticking to betting systems and strict limits.

I've got a couple buddies saying you can "beat the dealer" with discipline but it feels like sometimes you just get burned by variance or hit a cold streak. For me it’s more of a side hustle, small money in, small money out. I’m not trying to go pro or anything but I keep seeing posts about people making it work, which sounds almost too good to be true. Wondering if anyone here has real stories or advice about actually pulling off a consistent income, especially from stuff like live dealer blackjack or roulette, and not just slots.
