We're not talking about mass, we're talking about numbers.
We're not talking about animals, we're talking about all eukaryotes and all their cells and all their mitochondria.
Now you take all eukaryotic organisms, times the average number of cells in each organism, times the average number of mitochondria in each cell. Is that number equal to, less than, or greater than the number of bacteria in the world. I would say greater than, but I could be wrong.
If the number of mitochondria is more than the number of bacteria, would you agree that the mass of mitochondria is more than or not much less than the mass of bacteria?
If this is true, then the mass of eukaryotes must be far more than the mass of bacteria... but this is not the case!
Therefore, there must be far more bacteria than mitochondria.
