[Pokemon] How have Pokemons such as Magikarp and Psyduck survived even though they have little to no way of defending themselves?

Psyduck can actually defend itself just fine, it always knows Scratch and quickly learns Water Gun. They may also use flocking behavior for defense, like non-monstrous ducks.

Magikarp probably just run away all the time (they are pretty fast and have decently hard scales), and survive on sheer numbers like most schooling fish do.
