People seem to be forgetting that the Juubi that both Obito and Madara absorbed wasn't even the entire thing. The full Juubi is the one that possess the chakra of all the people in the world, as this chakra came from the Juubi/God Tree itself. Since Kaguya absorbed all of this chakra, she obviously had much more than Madara.
