Any one particular neutral mutation (point or otherwise) is very unlikely to become fixed.
But there's a couple of things that have to be taken into consideration:
The average number of mutations is one point something for coding genes (i.e., well over a billion for each billion individuals);
With recombination, neither of a pair of mutations has to actually become fixed in order for both to wind up together in one individual.
