Nine out of 10 traditional desktop/laptop PCs, maybe, but that's a smaller and smaller share of the computers people use every day.

That's probably true; unless things have changed recently, nearly all consumer PCs shipped with Windows for several years (and Windows/Office versions) have shipped with whatever the current "Home" version of Office is installed, though the license may have been a time-limited trial. So, yeah, if you are looking at installed, you'll get a pretty high number.
