If you read the post you've linked to, you'll see that it then evaporates right back out of the ocean, and even though most of it falls back into the ocean again, 10% of that evaporation falls onto the land as well. 10% is not as little as you might think, since 96.5% of the water is in the ocean. TL;DR: it's also not a one-way situation.
