A Star Cluster is a cluster of stars found within a galaxy or the intergalactic medium, and they don't usually have supermassive black hole centers or spiral arms. Star clusters contain around a thousand stars, compared to the Milky Way's 300 billion stars. In short, a galaxy is not classified as a star cluster.
