Is there ANY actual strategy in roulette or is it pure luck?

i see everyone claiming roulette is just 100% luck and that no system matters, but that seems way too simple for me. the casinos push that idea pretty hard too, but why would they if there wasn’t something they’d rather we didn’t see? i know the math on single number odds and house edge and all that, but that doesn’t mean there’s zero edge for players ever. if people can manipulate streaks or timing, or find subtle bias in real wheels, that might change everything, right?

anyone actually try tracking spins or mapping patterns for live dealer tables? online probably uses rng and maybe that’s harder to crack, but live games still have physical wheels. i feel like the market just copies each other’s takes and assumes it’s impossible, but i’d like to see some real data, not just hand-waving about “luck”. maybe the right approach isn’t winning every time, but finding little weaknesses and exploiting them before the casino patches it.
