Yes , your great aunt and your niece will share some but not all of your DNA. In fact, you will probably share much less than half with either of the, That is, of course, assuming that your great aunt is directly related to you, and not your aunt by virtue of being married to your great uncle.
It might mean they have an incestuous relationship. It might merely mean that the uncle is trying to share a private joke with the nephew.
Louis Tomlison and Harry Styles share a flat. Zayne Malik, Niall Horan, and Liam Payne all own their own, but all four of their flats are very close to each other.
If you are referring to Full House, then no they did not play Uncle Jesse's twin boys. They shared the role of Grace's youngest son Patrick on the sitcom Grace Under Fire. Uncle Jesse's boys were played by Blake and Dylan Tuomy Wilhoit. Hope that helps.
Your great uncle's niece could be your mother, or your aunt. It is also possible that she is not related to you at all, as you might not share a common ancestor.
