like it's a really big setting (whole galaxy) and even pre-empire the Jedi were a single religious order based on Coruscant. and yeah they could have other temples but they clearly don't have an established presence on every planet. plus latent force sensitivity is typically a pretty subtle ability (Anakin was off the shits powerful & his presented primarily as inhumanly good reflexes).
fully plausible to me that most people who don't live on Coruscant (or another planet w a Jedi temple on it) could very easily go through their whole lives without ever meeting a Jedi. less likely that they'd never run into anyone force sensitive but again 'force sensitive' could just mean 'weirdly intuitive' in practice
this is why it's not that implausible to me that as of the original trilogy a lot of people don't believe the Force is a real thing - even when the Jedi were relatively abundant i can believe that a lot of people were like 'oh there's a religious order who believe they have magical mind powers? that's neat I guess'. add in some imperial propaganda about how the Jedi and yeah sure. i can buy that within 20 years everyone's just pivoted away from believing in the force
anyway potential very sharp split in the rebellion between people who never believed in the force/bought into the propaganda/are just too young to remember the jedi order and people who are like no you guys the Jedi could kill people with their brains, I know bcos I was there
