If 100 kids played for 2 hours in one day you could say they have a combined 8 days of play time in a single day.

So the claim is that there have been at least 9 million hours played per day by an unknown number of "kids". That's... profoundly difficult to unpack from "more than a millennium per day". And I'm still not actually sure that's what they meant. Is this kind of construction common?

I understand "man-hours", but I've never heard words like "millennium" inserted like that.

If you wanted to use proper dimensions, you would more accurately say they had a 8 child-days of play time in a single day.

Messing up units turns sensible claims into gobbledygook.
