A possibility is different than a certainty. There is a possibility that life has developed on another world or other worlds, but combining that possibility with the number of worlds (billions? trillions?) still doesn't create a certainty. Because we don't know what the possibility of life developing is (besides 1/n, where n = the total number of planets in the universe), we cannot apply a statistic to the number of planets. It's really that simple.
