Vector is some way to draw digitally. BUT you can kinda zoom in indefinitely. Like with pixels (which are normally used for digital art), you zoom in and get some fuzzy lines, but when you use vectors, they are created in a way that your computer can analyze them and will make them look sharp no matter how much you zoom in.
And for the look: Have you watched My Little Pony or know the style? That is vector. But you can do many more things with it.
