Of course not. Both Hindi and Urdu have undergone a fundamental change over centuries. Are you saying that the Urdu used by Ghalib et al is the urdu spoken today in everyday use?
Yes, its very similar to the Urdu you hear in the Pakistani media today, & used by average people (not poets or people into literary works) with a decent knowledge of Urdu. However, even you have to admit that Shudh Hindi is a creation of post 1947 India.
