I think you must be thinking of some other word — maybe the fact that "ice" doesn't necessarily refer to water ice. If a science article says "water," they generally mean water unless the author's phrasing is extraordinarily sloppy.

I think they will usually refer to this as "oceans" or "liquid oceans". The term "water" as far as I know only refers to H2O.

What other kind of substance is called 'water'? As far as I know only H2O is described as water.

Water usually means liquid H2O. Europa, for instance, isn't liquid water but ice that is squeezed and loosened to the point it acts like a liquid while still being well below freezing and basically just ice sand

Very cool!

The main part is that they found some type of material that is made of table salt and water https://en.wikipedia.org/wiki/Hydrohalite , real table salt and real water.

So they have tables! They must have life.

Ceres is by and large H2O (by volume).
