(Spoilers Extended) Show Euron seems a bit confused about who he is

First when he meets Cersei, he said he was chosen as LORD of the Iron Islands. Moments later he refers to himself as KING of the Iron Islands. The next episode when he brings Snek and Mama Snek he says they are gifts from all of Cersei's loyal subjects on the Iron Islands. He can't seem to make up his mind about whether he's a King or a Lord.
