You'd be surprised. Research has found that the "digital native" generations (younger people born into/after the internet age) are no better at these things than the "older people" - the whole "digital native" thing is a myth in this regard.
It's mostly about being interested in tech/a nerd vs not. Kids that don't, might know 100 ways to use Instagram or specific tools they need, but can't tell a URL bar from a search bar (and other basic distinctions/skills) either.
