Should I be worried?

1960s 9 floor apartment building in Cincinnati, OH. Seems like prime years and fire-retardant material scenario considering the height.
Cable guy came over and started drilling holes, tracked dust on carpeted living room, and left me the mess to clean up. I was in another room when he started drilling.
I didn’t want to assume there was no asbestos risk. I had limited resources so I put on a kn95 mask and used wet paper towels to clean up the pile of dust since I read regular vacuum wouldn’t be good. Then I blasted my levoit 300 air purifier in the room the rest of the day yesterday.
Thoughts based on the images? Do I need to be concerned at all? Other advice welcome. Seems small right?
