Yeh I've thought about that also that the earth has so many elements, while the Hayabusa2 asteroid is mostly carbon star-dust. However besides oxygen we are made mostly of carbon. And for example the amount of gold on earth is likely the same rate all across the universe give or take (it's not super common).
