The information is inferred. The term is Rookie (ルーキー, Rūkī), but, as they are Hunters too, Rookie Hunter is acceptable. Kurapika also had no experience but was treated as Blacklist Hunter because since the beginning he had already chosen what to hunt, and every Hunter needs (sooner or later) to hunt something. Gon and Killua are active as Hunters but they don't have any "specializations" yet. Leorio is still a student and it can hardly be said that he did something as a Hunter; it's almost obvious what kind of Hunter he's going to be but, as you can tell from his words, he's still just a student.
