Yes, it's true that not all of them are. But the first line treatment is pretty much always a stimulant, and non-stimulant pharmacotherapies for ADHD tend to not be as successful.

The main class of drugs considered to be non-stimulant treatments for ADHD, NSRIs, will actually have a somewhat stimulant effect owing to their primary usage being that of an antidepressant.

In rare cases you may even prescribe a depressor, but that's something you very rarely want to do-- every case is different and these drugs may work for some patients, but generally speaking it's a niche treatment approach with a very unfavourable risk-benefit ratio.
