Suppose Serena Williams is a professional tennis player who has won a total of 23 Grand Slam singles titles, the most by any player in the Open Era, and the second-most of all-time behind Margaret Court. She is also an Olympic gold medalist and has been ranked No. 1 in singles by the Women's Tennis Association on 8 separate occasions.
Can we infer that "Serena Williams has won more Grand Slam singles titles than Margaret Court."? Yes, no, or maybe?
