I've never heard of a rolling hitch called a stopper knot. Stopper knots are
usually associated with preventing a line from going through something, such
as a fairlead.

2. what other knots should I know and why are these knots used?

Rolling hitch--also sometimes called a stopper knot. Useful where you need
to be able to adjust the length of a loop under strain, Primary use on
larger ships is to take the strain on a line such as a mooring line while
the line is removed from a winch.
