Roulette hot and cold numbers: is chasing them actually a strategy.

so every time i’m waiting for a slot machine at the bar, there’s always this group around the roulette table arguing about hot and cold numbers. some swear you gotta chase the last five hits and double up when they cool off. others just laugh and say it’s all noise. my gut says the wheel doesn’t care about streaks, but i keep seeing people walk out ahead - at least sometimes. when i play i just go by gut feeling and hope the dealer doesn’t spin me into next week. anyone see any real method behind following the board?
