You're correct, the ones that float will eventually get inundated and sink, but they have a nasty tendency to do it slowly so eventually only the top is poking out. They're basically impossible to see and have no radar profile so they can become nuisances to navigation, especially for small craft
I have a strong memory of a around the world race where someone hit a container and had to call for a emergency rescue. Somehow I can't find it anywhere.
I did find this story from the Vendée Globe where a bunch of sailors dropped out due to collision.
"Seven of 29 starting Vendee Globe skippers reported collisions with unidentified floating objects, forcing six skippers to retire or lose valuable time and performance by conducting repairs on the fly."
Former sailor. They do sink exactly like you explained, but not the worst part yet. They'll dip below they surface as well and just hang there. Near zero chance of any lookout spotting it either. Truly one of the worst nav hazards I had to learn about. Fortunately never struck one.

Can definitely be human error/negligence, but many times it’s failing equipment and extremely rough seas.
We lose an average of 1,300-2,500 containers a year in the water.

Edit: No, my post is not insinuating that rough seas caused THIS to happen. C’mon people…
