The difference has nothing to do with the knowledge.
In the stock market, the money put in is actually used to advance the value of the stock. It's an investment just like you paying somebody to make widgets (that manufacturer could screw up his work and lose all your money, but that possibility does not make it gambling). In polymarket the money you put in is not used in any way to advance the outcome you are betting on.
