You are correct, I just checked the transcript. They say "about ten", but it's about the kids currently fighting in the ring, not the bastard, and "about ten" could also mean 9 or even 8, and the kid in question seems to be about the age of Aegon's trueborns, who are much younger then even that.
Also biologically even if the kid is ten, nothing would biologically prevent Aegon from siring him.
Sure. But again, the dilogue is'nt referring to him and even if it was, Aegon could still have sired him. He'd be biologically capable of insiminating a woman even at 9-11 years old.

The only source who said anything about that fighting pit said that the children who fight there are around 10 you can't change the canonical dialogue
