Suppose Serena Williams, born Serena Jameka Williams on September 26, 1981, is an American professional tennis player and former world No. 1. She has won 23 Grand Slam singles titles, the most by any player in the Open Era, and held the world No. 1 ranking in singles on eight separate occasions between 2002 and 2017.
Can we infer that "Serena Williams has never won a Grand Slam title."? Yes, no, or maybe?
