The temperature of the water and the steam is the same. However, the amount of heat in them is different.
Water boils at a constant temperature, and when it changes into steam and escapes, its temperature remains the same.
But, the amount of heat released by water at 100 C is 4.2 J/g while that released by steam is 2268 J/g. This makes burns by steam a lot more serious than burns by boiling water.
