For males, the answer to this question depends upon a number of factors: If singles alone is to be considered, the most number of Grand Slam titles has been won by Roger Federer. However, Rod Laver is the only man in history to have won the true Calendar Grand Slam twice; further, the prime titles that he won when playing professional tennis have not been accounted for as part of the slam tally. Thus he also lost about six years of his best tennis to the ranks of professional tennis in a day when amateur and professional competitions were separated. On the other hand, if singles and doubles slam titles are treated equally, Roy Emerson has won the most titles of any man in history at 28 in total: he has also won the most doubles Grand Slam titles. Many in fact, consider him to be the greatest doubles player that ever lived. He also held the record for some time of the most singles titles held by a male player. For females, Margaret Court, at a total of 62 titles, undisputably leads the way as the greatest female player in history. She also became the first women's tennis player during the Open tennis era to win the Calendar Grand Slam in singles. She also won the Calendar Grand Slam in Mixed Doubles as well. At 24 singles grand slam singles titles and 38 doubles titles, she stands to claim the crown as both - the greatest ladies' singles player in history and the greatest doubles player. She is the only person to have won all 12 Grand Slam events at least twice - that is, all four major singles titles, all four same-sex doubles titles and all four mixed doubles titles. The International Tennis Hall of Fame states, "There has never been a tennis player to match (her)."
There are at least 3 who have won singles calendar Grand Slams: Steffi Graf, Margaret Court and Mo Connolly. Court has also won doubles Grand Slams.

You can play tennis at any age. Children play tennis in Ireland, as do adults. If they are good enough, they could try turning professional when they feel they could compete at a high level. They would be at least in their mid teens before they would do that.
Professional tennis tournaments - and other sports, as well - are called "open" to indicate that any professional player may make an entry, although, of course, not all will be able to play due to tournament limitations (e.g., 128 men and 128 women tennis players at a Grand Slam event). A "closed" event is one in which the tournament invites only certain players to play; these players are usually higher ranked and/or popular with the public (n.b., this is true of amateur and college level tournaments, as well). Technically speaking, all professional tennis events that earn players points on the ATP (men's) or WTA (women's) tour are "open" events to prevent anyone from being excluded from an event and, thus, not having a fair chance to compete and earn ranking points and prize money. Thus, the word "open" is somewhat superfluous, at least as far as the tennis spectator is concerned, and is, ultimately, little more than a marketing ploy.
