True — essentially. The Earth is almost a closed system for water, so the total amount (in oceans, ice, groundwater, atmosphere and crust) has stayed the same to within a very small fraction since the time of the dinosaurs. Geological processes, comet/asteroid delivery and tiny losses to space have changed the total only slightly. What has changed a lot is the distribution (sea level, ice sheets, groundwater), not the overall amount.
