A sociopath knows that he's doing something wrong and chooses not to regret it.
A psychopath otoh has a low neural activity in the area of the brain usually associated with empathy.
The main point being that being a sociopath is learned behavior.
Cf. https://youtu.be/6dv8zJiggBs
(I agree that disliking norms are not sociopathic. The norms might be sociopathic.)
(Also: I'm not an expert, I could well be wrong.)
Both sociopath and psychopath are terms stemming from the early 20th century, where our main concern was to lable people ASAP and prescribe them a "cure".
No professional psychology authority uses either of those terms today. Instead, you get ranked on the Antisocial personality disorder spectrum. This has several advantages, like having an actual statistical body of research behind it etc.
So your random YouTube video might not be wrong in a sense, but more like someone defining what "miasma" or "bloodletting" is: Interesting, but essentially just a talk about medieval medicine.
I would urge you to refrain from (especially) diagnosing people based on public wisdom on psychology.
