Technically, yes. However, this depends on how much dedication you have, and money you have for lessons. At 27, you are in your prime years athletically, so things should come easier for you now than any other time in your life. Being number one in the world is unlikely, but if you get lessons, win a few tournaments, and work your way up, you can qualify for a pro am tournament, and win that, and you can qualify for one of the big tournaments such as the US open. You'll play a lot of matches to get to the "big dogs" but with a lot of skill, dedication and stamina you can make it to the "pros."

all u need to do is to get training from a professional coach. if u take my advice, you'll soon b a pro!

probably, but why are you asking? you can do anything if you put your mind to it. but i don't thin i am the right kinda person to be telling you this cause i still have a good 80 years to go.
