    Displacement could be seen as absolute value.
    Displacement probably has to start at zero, while position can start elsewhere.

    It will depend on who uses those words in which way.

    No, they are not. For example, if an object is at rest in the reference frame, the displacement is a constant zero whereas the position can be any constant value.
    Displacement represent the change in position so they are different thing, in principle. They may happen to look the same if the original position is the origin of the coordinate system.
