Tracy is obviously a woman's name. Why did McGrady use it as a name?

Tracy is unisex, and there is a Tom in the American women's volleyball team. Foreign countries don't pay attention to men and women at all, but men are generally called xxx, and women are generally added YY. For example, many girls in America are called Robin. Robin is the name of a British robber (a man), such as Tracy, which is a very common name. However, in America, calling Joe casually is often less important. In the street, more than 20 people may turn around and call him casually.
