HELP ME UNDERSTAND! Trim Editing (Pixel; Sub-Frame)?

Help me out. My mind is trying to figure out the reasoning behind being able to trim by pixels. I'm also trying to figure out why you are able to edit on a sub frame level.

For example: (on a 24P timeline) If my timecode reads 00:0016:16 that means that I'm at 16 seconds and 16 frames. When I put my pointer at that frame on the timeline, I'm able to zoom into a point where I have 24 hash marks between 00:00:16:16 and 00:00:16:17. Meaning 24 more frames between the two points. What I don't understand at this point is why I'm able to either pixel edit (Number 4 key on the keypad), or just drag trim edit to a point BETWEEN any of these 24 hash marks. It doesn't make sense to me because in my mind I view that as a sub-frame edit (meaning I'm editing part of a frame). This doesn't seem right because it will just leave big gaps in your project.

Help all of this make sense to me. Why is this useful?

AUDIO - That's the reason for "Quantize to Frames" - so that you DON'T edit video sub-frame. Very useful for audio, though.

I don't get it. Everytime I engage "Quantize to Frames" my clips no longer snap to the grid markers. They come close but stop shy. What exactly is Quantize to frames and how does it work.

When I disengage Quantize to Frames drag trimming is smooth, and snaps back to the frame grid marker. When I engage Quantize to Frames drag trimming is not smooth but clunky, but it also snaps back to the frame grid marker.

What am I doing here? Somebody help me get this right. Please.
