They are obviously fat, and if we keep to the classification you posted we can call them severely obese. However they have way more muscle mass, for they not just need to be heavy but they have to move heavy. And they also have to be quick when necessary, although not all can pull sidesteps and spins well.
The most notable difference when we look at them, that how the "average" severely obese person's arms and legs puffy, but the rikishi's arms are thin, and their legs are very muscly. Their fat deposits are their bellies and tits. And even that ain't that big as those who are called severely obese.
If we would compare the 30 years of champions chart  with the current Makuuchi wrestles charts the distribution seems similar, most fell in 175-190 cm and 130-180 kg box.
Btw if you check the # of championships you can see Hakuho leads by miles. He was very quick too. Here's a  pic with a normal person. Would you call Hakuho severely obese?

Here's Abi's bouts from the last basho (8 mins):
