King's Cross and St Pancras are separate mainline stations. They're very close to each other (literally on opposite sides of a road) but separate stations. King's Cross also has a tube station underneath it that has a tunnel leading to St Pancras.

Your friend is wrong. To get a train to Manchester you need to go to St Pancras mainline station.
