Is it true that Mars contains water, mostly as ice at its poles and underground?

Yes. A NASA astrobiology overview and the Wikipedia Mars article both state that most of Mars' water is frozen as polar ice caps, and the NASA piece plus several peer-reviewed studies also describe buried subsurface ice at mid-latitudes and near the poles.
