The definition of a parallelogram is that it has four sides, the opposite sides are congruent and parallel, and opposite angles are congruent. This includes rectangles, squares, rhombuses, etc.
The definition of a rhombus states that it is a parallelogram, but more specifically that all sides are congruent.
So a rhombus is a parallelogram, but not all parallelograms are rhombuses.
