Now you're just reaching at straws to comfort your worldview. I could explain to you that I never was a huge gamer (and only started spending significant time gaming around 12 y/o), and that I am hugely uncreative (in the traditional sense at least) despite having played with dolls as a child. But I get the feeling that you'll just come up with more explanations why I somehow unconsciously "trained" the things I'm naturally good at.

Anything to avoid facing the fact that brains, like bodies, aren't all created equal and identical. To pretend they are is completely ridiculous. Yet we do so because admitting that not everyone is born with equal potential breaks through the veil of The Meritocracy™, Karma™ and all the other little lies we tell ourselves to avoid facing the fact that the world is fundamentally unjust.
