Diversity means "a range of many people or things that are very different from each other" (Oxford learner's dictionary), so the idea that a minority of people are "neuro diverse" and everyone else is "neuro typical" is not only semantically illogical, but also potentially offensive.
We're all different. Some people have traits that make life more difficult for them than others, whether it be ASD, ADHD or a range of other conditions, with spectrums of severity. Telling people that you're neuro-diverse is so vague as to be meaningless, and telling other people they are nero-typical when you have no idea what they're feeling inside is insensitive. Some people get a formal diagnosis for their symptoms, some people self-diagnose and others don't recognise it in themselves. Nobody knows how many people are living with these traits across the population, but the massive increase in diagnostics suggests they're a lot more common than anyone ever thought in the past, and therefore gradually becoming very "typical".
