Your estimate is late by almost 20 years - the first of that generation graduated high school ten years ago.
But the problem is that over those ten years google docs mostly feels like it’s been enshittified. Today’s office suites all suck I just want office 2007 or the google docs beta experience back - those were snappy and obvious how to use. Even basic stuff like linear regression in excel is terrible UX these days
And so mostly they don’t care to push it and if they do it’s not a material over modern office anyway.
I'm not sure if ChromeOS was also as pervasive 20 years ago as it is now. With its prevalence, the only office suite most students know is Google docs.
