None of the things you are saying have any bearing upon the mathematical argument. None of them are assumed, nor are they particularly relevant to the issue at hand.

Humans beings are different from bacteria. They have neural networks.

Perhaps there is something special about the human neural networks in relation to every other animal species on the planet which is necessary for consciousness. Perhaps a few animal species have consciousness. It is impossible to tell because the statistical argument does not apply to this situation where there are similar population numbers.

What is possible to tell (still) is that it is very unlikely that bacteria (bacteria is an objective category of organisms by the way, as is human, not subjective) have consciousness because of their vast numbers.
