why do some roulette wheels seem to favor certain sections

Been watching some wheels lately and it really does look like certain sections get hit a bit more than others. I’m not talking about streaks from just randomness, more like spots that seem to pop up every session. Maybe it's the way the wheels get worn down, or maybe the ball acts different depending on speed or humidity, I don’t know. You’d think it’s always supposed to be totally random, but what I’ve seen makes me wonder if anyone here actually tracks outcomes and notices something similar. Curious to hear if you guys focus on physical biases or just play straight odds.
