If you draw on a wall / table with a marker it will dry almost immediately and won’t come off easily, so how do whiteboards get around that?

It’s not the board. It’s the special pen. Mostly. Normal marker pens will set solid on a whiteboard and won’t come off. Special whiteboard pens work just as well on any shiny surface, eg glass, as they do on a proper whiteboard.
