Poor sleep is not just caused by poor sleep habits. Sleep apnea, as an example, is a disability that causes poor sleep and often goes undiagnosed. ADHD is not a disability per se, it is classified by the symptoms and is not classified by any underlying cause.

I totally agree and that is why I dont understand why it is linking ADHD and sleep deprivation.

Because many people with ADHD have poor sleep habits, and it's a recognized symptom.
