There is a huge difference between the common stereotype of ADHD (just rowdy children who can't sit still), and actual symptoms and diagnostic criteria. The difference is almost as comically warped as an image of a "hacker" in media vs actual hackers.
ADHD includes many other things like weak short-term memory, defunct perception of time, hard to control hyperfocus, overwhelming inner monologue, and executive dysfunction that makes some tasks physically impossible to start even when the person wants to do them. And it comes with a bunch of other comorbidities. Doctors diagnosing ADHD also have obligation to exclude other causes of the symptoms, like bipolar.
The stimulant medication does not actually cause stimulation in people with ADHD. When people have a deficit/insensitivity to the neurotransmitters, the meds merely bring them up from a dysfunctional level where the brain lacked ability to function properly to the normal-ish level.
