There are also many types of ADHD and also severity - a spectrum like you say. Probably everyone with it do not need major medication. But it is still probably valuable to diagnose everyone who is so they can properly develop habits to aid it. The biggest thing I ask people about is the executive function aspect. Are you simply getting distracted because you are bored or do you also find you have tasks you legitimately WANT to do but for some reason your executive function does not allow you do it. That seems to be (as a lay person) the biggest tell for someone who actually has ADHD.
