When watching a video we always subconsciously swipe the mouse to the right so the pointer can hide on the right side but it will always rest against the left side completely visible why is that?

The only actually important part programming-wise is the single pixel at the top left of the default graphic that lines up with where you’re clicking. That single pixel is the only thing that must remain on-screen to click things, so is the only part of the cursor that cares about where the edge of the screen is, and is by default the pixel at the very top of the left side.
You might notice that when you hover over a text box and are going to click where you want to start inputting text, the cursor changes – for mine, the single pixel while it’s over a text box is set at the dead center of the new graphic.
As such, it doesn’t have to always be that top-left pixel and can be customized, and in fact cursor customization was a regular practice when I was younger – there were a lot out there that clicked on, say, the bottom left, or had a little animated character chasing the cursor around trying to mop it up.
