That's very speculative data. Nobody knows what the 'habitable zone' truly is, but that's probably based on the temperature of liquid water... which could well be wrong. I mean, Europa is said to be capable of sustaining life, and that's miles out of the habitable zone there, so the thing clearly doesn't allow for any kind of realistic estimate. And anyway, those zones are hardly 'tiny', they look like they're more than 10% of the total space. So instead of 10,000,000,000,000,000,000,000 habitable solar systems we only have 1,000,000,000,000,000,000,000... and that's supposed to make life unlikely? Time to rethink your argument.
