They have the same function and every other type of light refers to them as a ballast, even the newer electronic power supplies for Neon and Argon are called Ballasts with no Iron core transformers needed since the late 1980s.
LED power supply are more like power supply, the in the simple form create a direct current.
Ballast have the ability to create a boost, and only make a square wave.

The way that it was explained to me it that “driver” is shorthand for “constant voltage driver” and ballasts provide an initial startup voltage the is different from the constant one they go on to provide.

Sounds kinda like how your car will draw a few hundred amps to start but it’s fairly low after that.
