Furthermore, that argument is even more powerful when used against gods than it is against abiogenesis. Whatever the chances of the parts of a tiny, weak, fragile, mortal, unconscious cell finding one another are, the chances of a sentient, volitional, omnipotent, immortal, omniscient, omnipresent and perfectly moral entity existing dwarf that.
Can you describe anything less likely to exist uncreated than that? I can't, and I'll bet that you can't, either.
Even a race of such creatures is more likely to exist than only one, unless it cannibalized all of the others.
