This explanation is denotatively correct, but connotationally wrong. Neurotypical, as most people use it, refers to someone who has a "typical psychological makeup," in contrast to, say, an autistic person, a person with ADHD, or a person with certain mental illnesses, not in contrast to, say, very high IQ people, adept meditators or people who like pineapple on their pizza. People with vanilla depression and people who are broader autistic phenotype or subclinical to another thing-agreed-to-be-a-neurodivergency are in contested territory wrt their characterization as "neurotypical."
