I have a pretty basic understanding of coordinates and can comprehend the X and Y axis relatively well, but the Z axis is where I fall flat. Like what does it represent?? Its for 3D stuff I’m pretty sure but thats about all I know about it.

Horizontal and vertical position and depth. For reasons that do not matter now there were different systems that change one axis to the other (eg use the Z axis for height and the Y axis for depth instead of doing it the other way around). It really is changing a letter, but the concept they represent is the same.
It’s like walking, you can walk forward and backward (Z axis), left and right (X axis), and up (jump) and down (crouch) (Y axis).
