Those are different things.
arm talent is always used as a substitute for arm strength.
the other stuff, accuracy, awareness, ability to make throws from all angles and on the move off balance etc. are all different traits.
when guys drop balls in the bucket like Allen’s incompletion to Kincaid last week that is accuracy or touch, not arm talent.
its a goofy term that exists for no reason except somebody used it and then everyone uses it to justifies its existence.
its pretty much like David Cross’s fantastic bit on “Timemug”
