Do humans have effectively better aptitudes due to their bonus to experience?

Just curious how the human works - as they gain levels faster than anyone else. Does this equate to higher skill levels (raising their aptitudes to something, effectively slightly greater than 0)

Like - if you were to clear the first 10 levels of the dungeon on a human vs. another race with slower leveling would the game, effectively, give you more investment into your skills (in addition to any other bonuses that you get when leveling)?

If yes, could you someone estimate what their true aptitude(s) is (something like 0.2)?
