And that's absolutely fine. Don't try and play their game, just be in the moment and let things wash over you. Accept you don't understand people, they aren't a thing to figure out and pick apart.
Trying to min/max human interaction is more for sales, marketing and management people, and those come across as absolute psychopaths. And I'm confident you see right through their schtick, because you are more observant than a lot of people - whether you realize it or not.
But yeah. Read up on things like introversion and autism to help you with personal acceptance, this will reduce the anxiety you may feel when interacting with other people because you understand yourself - and by extension, others - better.
As for basic communication skills, there's plenty of guides out there but it'll be things like "Listen instead of waiting for your turn to speak" (and realize there may be others who are waiting for their turn to speak without being as aware of it).
There's no panacea or This One Trick though. Social skills are a much broader, more complicated, and informal area of expertise than ML or other 'hard' skills are.
