roulette wheel maintenance and whether this actually affects fairness

so i’m mainly a blackjack guy but lately i’ve been hanging around the roulette tables just out of boredom. i keep seeing posts and vids about how the way casinos maintain their wheels can mess with the odds if they get sloppy. like if a wheel gets worn out or tilted even a bit, certain numbers could hit more often? never actually paid attention to whether places are checking for bias or swapping out wheels - i just assume everything’s on the up and up since it’s not some backroom joint.

has anybody actually noticed bias in person, or is this just one of those stories that gets blown up online? do you think bigger casinos take care of this or do they not really bother unless someone complains? curious if any regulars track outcomes and spot weird patterns or if that’s just tinfoil hat stuff.
