Do we know for sure that the ice caps are not already displacing the ocean water either all the way or a little and the rise in the ocean will not be noticed?

The ocean is already lower today than it was 165 years ago.

One of them is and one isn't. The north polar cap is already floating, so if it completely melts sea level will not change. The south polar cap is on land and if it completely melts and the water runs into the sea, sea level would go up something like 80 meters. And the ice sheet in Greenland is on land. If it all melted and the water ran into the sea, levels would go up another 20 meters.

The northern ice cap is floating so it really wouldn't cause much of a difference.
The south pole is a different story. Nearly all the ice there is contained in a glacier on the land. In some places it's nearly a mile thick. If it melts, it will cause a significant rise in ocean levels.

The Arctic ice cap is almost all floating. The ice on Antarctica and Greenland is almost all sitting on land. People have dug enough holes in the ice to determine those things.
By the way, Mr Jello is referring to one ambiguous mark on a rock. Thousands of scientific measurements all around the world show that sea levels are indeed rising.

it is a well known fact, but the ice in Antarctica, Greenland and other places is on land, and as it melts sew water will rise.

Yes. The icecaps are sitting on land, not inte water. Go look ata map.
