I don’t get the point you’re trying to make with your graph. Obviously there wouldn’t be many Zoomers working full time; most are still in school.
Zoomers born after 2006 haven’t graduated high-school, and those born between 2002-2006 are in college. That’s leaves only a 5 year window of people you’d expect to be employed full time.
The line for millenials looks about the same as Zoomers.
