No, voltage measures how much work is done BY a unit charge going through those points (or conversely, how much work must be done to force the charge to go through those points in the opposite direction).

But isn't current the same throughout the entire wire? Why would there be a difference in PE? Oh actually, I think I'm getting messed up between potential different and change in potential energy.

No, that's not the confusion you're having, because there ISN'T a difference.

So..voltage measures difference in required potential energy per charge between two points?

It's either "required potential energy" or "difference in available potential energy".

Take some time to reflect on the points I've made above, and if you still have questions, ask again, but I think the change in perspective might answer a lot for you.

If "brightly yellow sun" means the sun is brightly yellow, then does "starry blue sky" mean that technically, the sky is starry blue? Although, maybe people normally put a comma between starry and blue :/

"Starry" is an adjective, not an adverb. If it were "starrily blue" then you'd be right, but I just made that word up right now.
