Stephen Smale scored a Wolf Prize, a Fields Medal, a Sloane Fellowship and a slew of other accolades off the back of mediocre grades at the University of Michigan (a fairly decent public research uni I've heard but not as far as I know an "elite" school).
Looking around there's many a high achiever that missed out on a US Ivy League placing.
Don't know if Smale is a good example to use, since he did this 75 years ago! Back then the CUNY schools had similarly impressive graduates due to quotas at the elite schools. And Michigan is also a public ivy, though I'll concede it's more achievable to get into Michigan compared to Princeton (far more egalitarian in this regard).
I'll be honest, I'm sure there are some high achievers that missed out, but I haven't met a single one. Most very high achieving people I know that didn't go to top schools at least got into one (and usually multiple). I don't think there's any hope for my class of people.
I don't know what subset of society you live in, but the university you attended is not commonly brought up in America. If you're referring to your intellectual aptitude rather than the credentials attached to your name, just try to be a good person and do the best you can with what you've got.
I’ve lived in America all my life, and it isn’t commonly brought up in my American peer group.
You’re also conflating the perception of intellect with the actual possession of it. It seems like you don’t have much confident in your measure of either. Maybe find a therapist. Help with this is beyond the scope of HN comments.
There are countless people who have not attended a top tier college, e.g. people who might be regarded as “intellectually inferior” who are richer than you and I. Meditate on that.
