Can we agree that they are just lucky shots? I've been playing 20 years and i've had a lot of lucky shots.
Some aces are lucky shots, but most of my 30-some aces have been calculated, in the sense that they were air bounces deliberately thrown on the intended line with just enough speed and height give them a chance to go in, and would have settled no more than 20' from the basket if they hadn't.
You can argue that hitting the intended line with just the right speed and height is luck, but I prefer to think of it as skill.
