Not every short quippy explanation is correct...

That's half the problem we face - people equate simplicity with absolute correctness or they internalize things as universal when something is drowning in nuance and situationality. Half of how science has changed in the last half century is a change from trying to understand perfect absolutes to getting down and dirty and figuring out and embracing spectrums and variations. The desire for simplicity does not serve. The catch all explanation is at best a placeholder that is incorrect but better than nothing and at worst it's a siren song that leads you to damn yourself into believing a very untrue picture of the world.
