In the recent chapters, it was revealed that the IT and the God: Nativity of a World of Trees were responsible for the mutation of a human into a White Zetsu. When Hagoromo sealed Juubi's husk (that had Kaguya as well) he also sealed those cocoons of the G:NOAT that were stored in the Gedō Mazō. So there had more than 100000 zetsu stored there.
