What I’ve read online says that Vector art uses math to make the image scale better but isn’t ‘math’ used in Pixel art in, say, Photoshop as well? I’m having trouble wrapping my head around how the math might be different when creating a line in Photoshop vs Illustrator for example.

Vector graphics is like drawing with a pen.
Pixel graphics is like capturing the image with a camera (or looking at a scene with your eye).
If you know how to draw with a pen, it’s easy to know what it looks like. After all, if you know how to draw something, you can look at the result of that thing with your eye. That’s vector graphic -> pixel graphic conversion.
But the opposite way is not easy. If you look at a scene, can you draw it with a pen? There are no obvious method. Clever algorithm or intuition let you do this, but it takes a lot of work. That’s pixel graphics -> vector graphic conversion. Our brain is an incredible machine that let us do that, which form the basis of many visual processing task that human can do easily; that’s something that modern neural network can barely do.
You never “see” vector graphic directly. What you see on a screen is a pixel graphic rendered from vector graphic, plus some extra schematic.
