If you’re saying it like it’s you, you say “ a mi me gusta ( and then the thing that you like)” if a friend is saying it, it is “ a el/ella le gusta (thing that your friend likes)” If you refer to a group of people it is, “ a ellos les gusta”. If you want to refer to someone by saying you, it is, “a ti te gusta” or “a usted le gusta” fancy you basically If you’re trying to say I we like it, you say “ a nosotros nos gusta”
