Can one stand on pressurised water?

In a movie, I saw a submarine with a small hole at its bottom, through which the people inside observed the water and engaged in various activities. This got me thinking: since we can’t stand on water because it is too light, could we stand on highly pressurized water, like that found deep in the ocean? I understand that the pressure at such depths would be lethal to a person, but if someone were to enter a submarine with a hole and place their foot on the water from that hole, would they float, or would something else happen?

No, they would still sink. Water has pretty much the same density for a very large range of pressures. The pressure at the deepest part of the ocean is 1,086 bars, and about 1 deg C. The density is only 0.3% more than at the surface.

In other words, it’s very cold, but still practically the same density. You can’t stand on it.
