From the 'phased rollout' link in that source: "...Enterprise and education users will not be automatically upgraded at this time...".
From my observations over multiple machines (both physical and virtual) it would seem that Pro is also not being automatically upgraded yet. Most of my Home machines have had the automatic upgrade by now, whether running W10 version 2004 or 1909. None of my Pro machines have seen it.
I have also observed that all Windows 7 machines see the Edge update in Windows Update as an Important Update, while in Windows 8.1 it appears in the Optional Updates list.
