Judgment dragon special summon

Hey everybody, I’ve been working with a lightsworn deck for the last couple of weeks. The question I have may be a dumb one and have a very obvious answer; but I figured I would double check with everyone here as well so that I know I’m playing the card correctly. When I special summon judgment dragon, I can pay 1000lp to destroy all other cards on the field. Does that mean mine as well? Thanks in advance!
