Back to the start. Are you saying the two buttons are labeled, "Later and OK," and "Got it"?
Under much of Google's stuff "Got it" generally is a "Saw the notice, dismiss it," action button, while anything containing "OK" is a "Yes equivalent" button.
I'd be far more inclined to hit "Got it" and clean up apps afterward, which is an easy task.
I also have to add that I find it well-nigh impossible to believe that you have downloaded nothing in two years unless this device has not had any connection to the internet at all. While I can believe you have initiated no downloads yourself, Samsung routinely self-updates its software and sometimes adds new bits, and this screams the adding of a new bit by Samsung.
