Hera said in The Son of Neptune that Percy was part of the seven demigods of the Great Prophecy. And i'm sure that Annabeth is one of the seven since she got a POV. Nico is not part of the seven, he is just important to the quest. Just because Percy and Annabeth are not there at the moment, doesn't mean that they're no part of the seven anymore. They are just doing things a little differently than the others, that's all.
