I haven't crunched the numbers for ZZZ but I'd guess it's similar.

Note that when I say the expected value of limited 5*s from launch to 2.2 is enough to get every 5* on average, it means half the people who meet those conditions wouldn't quite get them all (and half would have a little extra left over).
