Mutable means you can change it internally. You cannot change the number 5. It is just plain number. Nothing in there to change. Objects you create are usually mutable. You can change their contents. Hope that helps.

Yes you can consider the immutables as constants they are just what they are. But lists and variables you can change by assigning new values to them
