nah they don’t seem to roll updates all at once, i’ve had two win10 machines a few years ago (started from same fresh install iso) and they always got auto updated in different day.
this was before the 7day(?) delay option appeared, there was no config. and in many cases the update wasn’t shown on start menu and shutdown/restart looked innocent until i clicked them and it started updating lol. i later just killed wupdate permanently via registry from safe mode.

That would likely be the default settings trying to avoid times when you normally use the machine to install the update.
