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.

Sounds like “percentage points” provides less information to the viewer, which explains the context I most often see it used.
