The distance between peoples ischial tuberosities does differ, but like I said that difference is very small. Less then 2cm. This is usually found in women having the larger distance. The set up of the bicycle it self and the height of the saddle in comparison to the handle bar, as well as the firmness of the saddle have a much bigger role to play in comfort.
