That's because diagnosis is geared to those people. Adults who cope relatively well in most situations don't know they have autism, don't seek a diagnosis, and there isn't a dx service available to them if they do know what to ask for.

Females in particular, are badly underdiagnosed.
The autistic people you know are the lucky ones. 80% of people with autism have intellectual disabilities(low iq) and as many as 50% are non-verbal.
It's more than not wanting to be someone perceived as quirky or strange.
