Even if the probability for this to succeed is really really small, there's a good chance it will happen when you have billions of years time and idk how many orders of magnitude (10^40? 10^50?) of atoms/molecules constantly interacting.

No, that's not clear at all. The smallest known system capable of independent existence and Darwinian evolution has billions of atoms. A mere 40 or 50 orders of magnitude is trivial compared to the unlikelihood of this arising by chance.
