Yeah, “percentage points” is used to refer to a difference between two percentages.
For example, let’s say some company previously held 25% of the market, but grew and is now holding 50% of the market. The company’s market share actually doubled in size, which we could call an increase of 100%. Or, looking at it another way, because they grew from 25% to 50%, you can call it an increase of 25 percentage points.
Whoa do “percent” and “percentage points” actually refer to different things?

Sounds like “percentage points” provides less information to the viewer, which explains the context I most often see it used.
Yes. If you have a half full battery it’s at 50% full.
If the charge goes up by 50% you get a 75% full battery.
If the charge goes up by 50 percentage points it goes up to 100%
