Suppose Serena Williams is a 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. Her victories include seven Wimbledon singles titles and six US Open singles titles.
Can we infer that "Serena Williams has never won a Wimbledon singles title"? Yes, no, or maybe?
