does Habitable imply inhabited?
First, so far we don't have a clue if the planet is habitable yet, only that it happens to be within what we describe very loosely and very likely incorrectly as a habitable zone.
If we look at our solar system using the same criteria there are three planets in the same zone, but TTBOMK only one has life. It is possible that the other two might be able to be terraformed to make them habitable but that would be a big, long term effort. Of the two, it is possible that with an intensive century long process we could make Mars habitable which might even be faster and cheaper as an option than extra solar planets.

Re: does Habitable imply inhabited?
The issue is that the zone is only one factor. Being in the zone only implies that ONE criteria for life as we know it has been satisfied. It says nothing about the likelihood of it being inhabited. In addition, the zone was a very, very early rough estimate about where life might be possible. As we learn more and more about where life actually exists we are discovering that the zone may well be totally irrelevant anyway.
