1/10 million species on Earth being intelligent doesn't really imply that 1/10 million planets with life would have intelligent life. Any planet with life undergoing evolution may also develop millions of species, with "intelligence" being an important trait for some of them. Problem is, that tells us nothing about how many planets could sprout life in the first place.
Even right now on Earth, we have multiple tool-using species spanning mammals, birds, and cephalopods, separated by hundreds of millions of years of evolution. They all seem like good candidates for developing technology at some point over a few million years.
