Yes we have very similar DNA to chimpanzees, and that similarity is demonstrated through similarities in our behaviours, anatomy and physiology, compared to more distantly related species.

"Certainly people born at similar times and places will also have very similar charts, and therefore very similar potential and tendencies"

Therefore if we compare people born at similar times and places, there is an increased chance that they will display similar traits compared to people born far apart and who therefore are supposed to have different tendencies and potentials. Nobody said anything about them having to be identical, just that for astrology to have any validity, they should be more similar than two randomly chosen people.
