This is completely false for the majority of places I've worked. Plenty of people don't notice how much they've got stuck, or don't know who the right expert is, or feel self-conscious about interrupting them to ask a question. Having a daily scheduled time where all the experts are available and everyone should check whether they're getting bogged down is a big help.
I've experienced the kind of "standup" you describe too, but it usually coincided with not actually following the rules for what a standup is (e.g. not actually standing up) and a bunch of other fake agile.
