Uruk is the Elf name for them. Goblin is a generic word for boogeymen the Hobbits use when they first see them. Uruk properly translates to Orc in Westron, the commonly used language of Men of 3rd age in the books/movies. Uruk-hai are basically high orcs, ie a brand new breed of superior orcs that didn’t exist back during the Hobbit. Maybe a small handful of the first ones, but more likely he hadn’t started or at least likely hadn’t perfected them yet.
