Never let anyone place limitations on what you can and cannot do. That is up to you.
With that being said, if you want to be a pro it is not going to be easy. Most pros started playing anywhere from 2 to 6 years old and at a certain age they are playing 6-8 hours a day, 6 days a week. They also usually have a full time coach or relative who can guide their training. If you do not have an expert fixing the problems in your game, you are going to waste a lot of time reinventing the wheel at best. At worst you will develop bad habits that are next to impossible to fix. If you want to have any chance, you need to practice 6 hours a day on the table, 1 hour of serve practice and 1 hour of physical training.
When I went to train in China, one of the women's national team coaches told me that if a player had Waldner's natural talent level, they could start training full time at age 16 and get to a decent level of playing. Otherwise it is better to start when you are 2-6. Not many people are as talented as Waldner, its a very short list of 1 person. But maybe you can do it, so try your best! Good luck!
