anyone actually making money from sports betting consistently?

I bounce between blackjack and sports betting, and honestly, I’ve had decent streaks in both, but nothing that holds up all year. I feel like I get up for a month or two, then just gradually give it back. Tried the “smart” stuff too, like spreadsheets and tracking units, but unless I’m only betting favorites, I usually slide back to zero or just a hair above.

Feels like the stories of people actually making a living off this are either half-lies or they have a massive bankroll and some wild self-control. Not saying it’s impossible, but in all my years messing with this stuff, I haven’t seen anyone in my circle who’s up consistently over a couple years. Wondering if I’m just missing something obvious.
