so am I correct in saying that it is water? I don't need percentages.

Well if it's over 50% that means it makes up the biggest part.

Yes, you are correct. By mass, most of the human body is composed of water. Water makes up about 60% of our body weight. So, it can be said that water is the largest component of the human body in terms of mass.
