I'm actually not very sure about the possibility of all Uchiha possessing bits of Indra's chakra. I think it was neither stated nor implied. We only know for certain that every Indra's reincarnation surely inherits his chakra, and if this chakra is combined with that of Asura (or, rather his reincarnations who inherit his chakra as well), it leads to recreation of Hagoromo's own chakra.
