I see this a lot working with grad students and professors. Older than a certain age = much more likely to have less experience with computers as they didn't grow up learning how to use them/only learned specific tasks and applications as needed for work and online communication/shopping/etc. Younger than a certain age = much more likely to only have experience with mobile, "apps", and turnkey solutions. Knows the details of popular platforms but little in terms of troubleshooting, workarounds, or generally anything that can't be solved by clicking a link or pointing to a picture on a screen. Granted, there are loads of exceptions because, as you say, there's nothing stopping you from learning about something if you have an interest. It's more a matter of who has run across a need to look into something in the course of their life. If you grew up in the period between personal computers becoming common and the explosion of web apps/mobile devices, chances are you had to figure out how to do something at some point. That's not necessarily the case before or after.
