Suppose Serena Williams (b. September 26, 1981) is an American professional tennis player who has won 23 Grand Slam singles titles, the most by any player in the Open Era. Williams has also won four Olympic gold medals, as well as numerous other prestigious tennis titles. She is widely regarded as one of the greatest tennis players of all time.
Can we infer that "Williams has never won an Olympic gold medal."? Yes, no, or maybe?
