Barring accidents/enemy action, yes it does seem that each incarnation of a Time Lord lives substantially longer than a human.
- The fact that the Eleventh Doctor has been around for nearly 200 years shows that Time Lords can live for a very long time. He began his life at 906 in "The End of Time", part two and is at least 1103 years old as of "The Wedding of River Song".
Also the first doctor looked old at the time he regenerated so he must have been a fair age at the time.
That doesn't really add anything. He looked the same as a normal human would if they were old. The original answers summed it up. That yes each of the 13 lives is potentially longer than the one potential lifespan of an average human.
