When putting tires on a personal vehicle it’s always recommended to tighten the lug nuts in a star or criss-cross pattern, yet when you see pit crews for nascar they just go around one by one very quickly in a circle, why can they get away with doing it that way even though they’re driving much faster so things like a loose lug nut or vibration should be a pretty big deal, but it’s recommended that I always do a star or crisscross pattern?

They are trying to change the tires as fast as possible. Nascar had to make a rule to require 5 lug nuts be installed on each wheel because teams were only putting on 4 trying to shave fractions of a second on tire changes. They do sometimes get a loose wheel and vibration might get so bad they have to pit again.
