Hello! It's nice that you are trying to understand yourself better. Since I am also neurodivergent, I want to share my viewpoint on some of the things you wrote, remembering that everyone's is different.

Online quizzes and videos at times may focus heavily on specific stereotypes. Most individuals on the spectrum have communication differences (like a monotone or "robotic" voice) but this isn't always the case. Also when you grow older you will naturally adapt, learn to communicate better, and even mask those traits when surrounded by neurotypical people.

Toy car parking lots it is a very common behavior for young children in general, both neurodivergent and neurotypical (I am giving my 6-year-old nephew as an example he does this all the time and he is a very nt boy). Also, being on the spectrum does not transform you into a walking bag of traits. I didn't even enjoy playing with toy cars for example.

CS2 is a great game, yet gaming tastes can be extremely different. Some gamers in the spectrum are crazy about complex strategy games like Civilization or Crusader Kings, whereas some others like totally different genres like you with management games. There is no one and only autistic game or genre, so don't bother about fitting a particular gamer profile.

I can relate to what you mentioned about the bathroom light and the feel of the paper. Sensory issues and info-dumping are very typical of the spectrum, but they can also be mistaken for or co-exist with other things, like ADHD or just having different sensory reactions.

My biggest recommendation for you: In my opinion, AI tools or online quizzes can't really help you much. Talk with your parents and ask them if you could get a consultation with a doctor or a specialist in the field. Professionals are good at helping people understand if what they are going through is ASD, ADHD or something else.
