Of course there are little differences, but in general the two kids will beat the crap out of 99% of the players that start at a later age. Moreso, the difference between these two kids will never be big as long as they both play and practice the same amount.
At the top level, all the guys can play the disc well. It is more about the shape you are in that day, how much you like the course, and most of all the mental game. Still not talent. All the guys at the top level have a feeling for the disc, all of them have worked long and practiced alot. You can ask any top athlete, it is all in the head. They all have the muscles, they all have practiced for ages. Look at olympic ski racing, the difference is often less than a tenth of a second, and they ALL say that it is in the mental game. No wonder that they all have mental coaches.
"In training everyone focuses on 90% physical and 10% mental, but in the races its 90% mental because there's very little that separates us physically at the elite level".

"I wouldn't say anything is impossible. I think that everything is possible as long as you put your mind to it and put the work and time into it".

"A world record is 99% training and 1% talent"
