"What is the line between Pokémon and people" is one of those questions you just shouldn't ask. Like "what is the food in the Pokémon world made of, do they raise Pokémon as livestock?" and "are the trees non-sentient Grass-type Pokémon?" and "if Alakazam and others are so intelligent, why aren't they the dominant species on the planet?" and "why is this child giving commands to a creature that can destroy the world, and in fact in many cases came close to destroying the world in the story itself?" Just...don't. Don't answer any of those.
