pilot is just the same as episode 1 of how do you play
Korean variety shows often do this, where they show one episode as a pilot to test whether people will like it and if the response is positive they get the green light and produce the show as a full TV show with 10+ episodes. If not, then they scrap the plan for the show and only that episode remains.
Because of this, often times, some time passes before they start the show, so they use the same pilot episode from before as the first episode when they restart the show. Sometimes they change a couple of things in that episode, and sometimes they don't. In this case, the episode length is also longer than the pilot episode.
Bottom line is that the pilot episode was aired much earlier and works as a standalone show in a way, so it wouldn't be smart to delete it.
