雕像 (diāoxiàng) refers specifically to a finished statue or sculpture as a physical object — a carved or molded three-dimensional figure. 雕塑 (diāosù) is the broader term for the art or practice of sculpture, and can also be a verb meaning 'to sculpt'. 雕刻 (diāokè) focuses on the act or technique of carving/engraving, or the resulting carved work, often on a smaller scale or with finer detail.
