That's literally correct for ADHD, yeah - the diagnostic criteria for it is all stuff like "patient says they have difficulty organizing tasks", which, naturally, depends a lot on what kind of tasks they're doing.
That's why ADHD is very common in concentration-requiring professions like software engineering (naively you'd expect the opposite) - there's people with "undiagnosed ADHD" (low concentration) everywhere, but if you're in a profession like that you are much more likely to have it impact your job, and go to a doctor, and get a diagnosis and a prescription of Adderall or some other kind of amphetamine.
How did you notice that?
