She has been well trained by apple they supply schools with equipment.
That isn’t quite so much the case any longer - a couple of decades ago - a school computer lab (if they school had one), likely had a room full of Apples of some variety. Apple was offering fairly “sweet” deals to schools (and they machines were just easier to set up as a lab at the time). But as time has passed, and cut-throat, commodity computer pricing wooed education dollars, Windows-based labs have taken he majority of such computer spaces in public schools. Add to it the initiatives by Gates and others to tuff even more MS devices into schools and Apple has lost its sales edge in education.
I would venture the associated Apple hardware (iPods/iPhones) have fed the growth as much as anything (that and frustration by many with Windows + associated malware and issues).
