So, practice accounted for 50% of success; working memory accounted for only 7%.
Of course talent matters. Hard work matters more.
A hard worker with less talent will beat a talented slacker [tortoise & hare]. But a talented worker beats everyone. No surprises here.
However... if you work hard, other talents you do have may eventually find an application/be revealed [ugly duckling], because depending on the situation, a flaw can be a gift (and vice versa). So in hindsight, it may turn out that you were the talented one after all.
