So now age is an issue.
Your affirmation is incorrect because even if someone train longer than another it doesn't mean he would be stronger, there is also the training methods who can be more or less effective. Ging is also more talented than Silva. Killua is the most talented Zoldyck in the history and he is as talented as Gon. Ging is possibly even more talented than his son.
Remember too that Ging is a Hunter, he traveled a lot and faced different situations. Silva is an assassin, he trained himself and just killed someone when people were hiring him( even if it was not a Nen user). It's more likely to think that Ging has more experience. If we follow your logic it would mean experience= power, it's wrong. With experience you learn to use your basic skills better and control your aura flow. Watch Gon vs Knuckle fight in the anime.
Nobody can predict Netero's actions because of his experience, his aura flow is calm and indecipherable. But by reading Gon's aura flow Knuckle was able to predict all his attacks.
