It's a meta thing. Pokémon has always played fast and loose with the fourth wall, for example in Gen 1 there are various NPCs playing the game you are currently playing on their Game Boys within the game and trading Pokémon between each other, and of course the Game Freak offices. This sort of thing has existed in every game since then. It doesn't *actually* exist in-universe, it's to communicate meta elements to the player.
