Yes, but there's always a desperate soul out there who's played it enough to max out the score. Just ask the Pac-Man players who reached the game's kill screen. Or those who got over a million points in Donkey Kong arcade.
Heck, just look at the shmup and bullet hell communities if you need more examples. Some real skilled players exist out there, and I'm sure somewhere in the world is a really, really dedicated Wario Land fan who managed to max out the counter in the Wario Hop without save states/tools.
