I learnt that ISS is always in a free fall due to Earths gravity. Since ISS orbits the Earth, does this mean Earth is in a free fall due to the sun because Earth orbits the Sun?

Actually we find ourselves roughly 1,5cm farther away from the sun each year. So instead of falling towards the sun we actually drift away.
The reason for this is that the sun loses mass. And this slight loss of mass results in a loss of gravitational pull. And thus we drift away.
