"Tatooine. Fascinating," Thrawn made a mental note to look up any artwork from Tatooine. "That is a desert planet, is it not? Darth Vader must have seen something in you for him to give you such an opportunity."

That Luke was set to serve on Vader's personal star destroyer upon graduation, to the point where the commandant feared Vader's wrath if Luke's were permanently assigned to the Chimaera instead, said a lot about how serious Vader was about Luke's career. Not many would take such a chance on a farm boy from an otherwise inconsequential planet. If Luke was indeed related to the late Jedi, Thrawn could certainly see why.
