Yep. Very hard. Possible to get to a semipro level. Possible to get to a lower level pro level. Could you get to a higher pro level like top 100 in the world or even top 2 in your country? Well, it is possible. But seriously not likely.
What Matt says has some merit. But, it is crazy how hard it would be.
But, could you get to the Olympics? I think the way the Olympic trials work in your region you would have to be in the top two or three in Central and South America and you would have to win your spot at the trials! That would be very hard.
I could be wrong but I think three players from your region are eligible to qualify. Same for North America. Three players can qualify. But the three cant all be from the same country, or, really, if three qualify from one country, only 2 can play singles. The 3rd qualifier, qualifies for the team event only.
But NextLevel is right. If you want to aim for this, start with a serious regimen of coaching and training.
You would need to be training with players that are pretty darn good. You would also need to be getting coaching from someone who is an elite coach. Well, perhaps need is not the right word. But that would really increase your chances.
2000-2300 (USATT rating system) is an expert amateur level. That would be darn hard but pretty possible.
2400-2500 would be semi-pro level playing. That would be extremely hard to get to but still doable. But this level is probably not good enough to get someone into the Olympics in most regions.
2600-2700 is a low level pro and if you are in the higher 2600s or lower 2700s you may have a good chance to get to the Olympics. Guys at this level are actually pretty amazing. There may be some regions in the world where a 2200-2400 level would get you into the Olympics. But I am not so sure. And that player would not be able to handle to competition at the Olympics in any meaningful way.
The top pros (like top 100 in the world) would be 2800+.
That realistically wouldn't happen unless someone started real training before the age of 10 years old.
