Let me ask an adult what that is or go look it up in a book/online myself!" and that's assuming they didn't already know what it was. Pretty much every blind/disabled people episode of pre-schooler cartoons explained it, it's widely used enough that everyone encounters it in their daily life and by time kids can read enough to play pokemon they're past that just learning phase where most kids start paying attention to signs and would have noticed the weird dots and asked their parents or teachers what they were/why they were there long before pokemon could be their first exposure to it, and by 10 years old most schools would have given a lesson on Hellen Keller and Louis Braille during world history or whatever part of the curriculum the school felt it best fit. This wasn't some obscure thing only a handful of players would've been able to figure out, the only difficult parts were stumbling into the right locations and interpreting the clues themselves because they're kinda weird upon first reading and don't fit the style of puzzles you'd be used to encountering throughout the game.
