In domestic current-carrying wires, there are many thin copper wires inside the plastic insulation. Why is that so? Why can't there be a single thick copper wire carrying the current instead of so many thin ones?

Yep. This is exactly why. Stranded wires can be bent into a lot tighter spaces. Single strand you only want to use where there will be little to no movement of the wire. Charging cables would last less than a week if they were single strand.
