That’s not the case where I live in the small non-American West.

We’ve all seen the American TV show/films where some Mega Loser has failed to move out the year they become eighteen and graduated the year they become twenty-two. Maybe it comes off as a trope for non-Americans.

In America, if you don't move out ASAP, you are considered a failure, a loser, a (wo)man-child, etc.

In other countries (or even cultural enclaves in the US), it's considered perfectly normal and acceptable. You'll see highly paid professionals like medical doctors, hedge fund managers or SWEs making huge salaries living with their parents.
