Hashes are uniformly distributed over the entire number space, so to answer you question, they are as random as they get. Furthermore, such hashes are routinely used in provably fair algorithms in other sites, sort of like an industry best practice.

Is there any mathematical proof of that or it is just an assumption based on previous data?

As far as I am aware, there is no "proof", not in the mathematical sense. Try this, make a list of numbers from 1 to 1 billion. Get the SHA256 (or any other) hash of these numbers. You'll see, the hashes are uniformly or evenly distributed. It's not perfect.

You can check the last digit and see if you get close to the expected results.
