Your camera's meter is not wrong. It is just average.
Point it at snow and the photo comes back grey. Point it at a face against a bright window and the face goes dark. Point it at a dark room and it looks strangely bright.
The meter measured the light correctly. It made a reasonable decision based on everything inside the frame. The problem is that a reasonable average is rarely the photograph you had in mind.
That is what exposure compensation actually does. It does not change how the scene is measured. It changes what the camera is aiming for.
