Statues and sculptures are commonly confused by layment, as the term is readily interchangeable...However, sculptures and statues are not 100% the same, as a rectangle is consider a square, a statue may be considered a sculpture.
That is to say sculptures are simply a representation of 3 dimensional art. They are a method for transforming a medium such as stone, resin, wood, marble, granite, bronze, plastic, and more. Sometimes sculptures are used as bookends. Sometimes sculptures are used in trophies. Trophy sculptures are quite commonly provided as awards in sports and also in recognition programs.
A statue on the other hand could be a sculpture, but its definition is not as broad. Is the Statue of Liberty as sculpture? You tell me. Its up for debate.
