It is the law of large numbers. It goes with the theory that if you buy 100 billion lottery tickets you asymptotically approach 100% chance of winning. In the case of abiogenesis, if you can show that the conditions for this effect were possible, and that those conditions could persist for millions of years, the probability that the "special" one occurs, approaches 100%. It doesn't explain everything, it is just a link in the chain of things that increases our understanding of our world.
