Good intuition. This document isn’t real medical research from medical professionals. It’s from a group of people soliciting donations and trying to sell neurodiversity trainings for organizations.

This comes from a part of social media where medical conditions are redefined in ways that make them sound more broad, generic, vague, and common than they really are. This is why this corner of the internet diagnoses themselves with many of these conditions together: The definitions they believe are like horoscopes where anyone who has non-specific symptoms or even psychosomatic conditions can match the definitions given. The result is groups of people on TikTok or Facebook groups who all think they have a list of 5 different medical conditions and who are all frustrated that actual specialists for those conditions won’t agree with their self diagnoses.

What's the context for that, I don't get it

A most logical and rational reaction.

Psychosomatic suggestibility is not on the list. These are also all chronic conditions, so if the descriptions don't match your history, you have nothing to worry about.
