This is true but Xerxes also made a generally poor decesion to march an army that sizr through Greece. They couldn't off the rocky unfertile Greek country side so the food and water need to support the army had to be shipped in or carried with them. And there lack of knowledge of the terrian ment the Greeks could, like at Thermoplye choose the best locations to fight as when as know when and where to run to avoid the advacing army. There was a reason Darius I choose to invade Greece by Sea when he invaded and that was becasue he knew that a large army marching though Greece, in the manner Xerxes did, would work well.
