Yeah, statistics isn't really good at extrapolation from a single sample. I think statistics is entirely bad approach to resolving this problem at least until we have more data. We need to know more about how planets form (again, we have rather small sample we have studied well), we need to know what exactly is necessary to jumpstart life and how likely it is to happen. Then we have a hard task understanding why exactly intelligent life evolved and whether it is unavoidable or a fluke. And a bunch other questions that statistics is entirely unprepared to answer.
