Suppose Serena Jameka Williams (born 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 the second-most of all time behind Margaret Court (24). She has been ranked world No. 1 in singles on eight separate occasions.
Can we infer that "Serena Williams has never won a Grand Slam title."?
