Suppose Serena Williams (born September 26, 1981) is an American professional tennis player. She has won 23 Grand Slam singles titles, the most by any player in the Open Era, and the second-most overall behind Margaret Court (24). She has been ranked No. 1 in singles by the Women's Tennis Association on eight separate occasions over the last 19 years.
Can we infer that "Serena Williams has won the most Grand Slam singles titles in history"? Yes, no, or maybe?
