> pokemon is a game where you can win but you can not lose
As I recall, there are several ways you can lock yourself out of being able to complete the game (releasing unique pokemons, primarily), so there was a good deal of trepidation & danger when it came to some critical moments and when the trolls got the upper hand.
You are correct, there are ways to do so. There are also soft-locks which are states which are just incredibly hard to get out of (heat death of the universe type scenarios some times). Pikasprey yellow is one youtuber who chronicles things in that area.
But I think the commenter above meant that Pokémon was a game which was possible to complete in a twitch plays style because it doesn't result in game over like an FPS or platform we would for example.
It's a tad harder than that. "Common" softlocks generally put you in the elite 4 rooms, with 1 pokemon that is underleveled and knows splash, with all others released. These elite 4 rooms are generally the only rooms that you can enter but not leave (except by beating the trainer or losing), and then you create additionnal constraint to prevent a combat loss from freeing you, like purposefully not picking up a lot of optional items that would make it easier to bounce back.
