Short answer: Yes, there is definitely such a thing as talent. But whether one decides it exists or not makes no difference.
Long answer:
Discussions like this always end up being issues of semantics. After all, whether talent exists depends on how you define it.
Everyone has a different idea of talent. When some people think of talent, they think of a child prodigy with great technique but little musical maturity. But when others think of talent, they picture those who, without any formal musical training, without even knowing how to read notes, are able to learn to improvise on the piano, which is something that many with training cannot do. Other people think that talent is merely the passion and dedication required to work hard. Each person's idea of talent isn't right or wrong, but just a part of the picture.
Because great musicians must (and do) possess "talent" in every area. No pianist ever became great without dedication or passion. Or without an ear for musical expression. Or without good technique. Or without efficient practice methods.
If I had to, I'd probably break down the influences of talent something like this (based on pure speculation) :
20% inborn traits
30% upbringing
50% personal choice
