Somewhat simplified, but probably something along these lines.

Tightening the packing gland compresses the packing rings against the shaft. Sort of a trade off between keeping the water out and making the packing so tight that the shaft can't turn. You'll always get some seepage. Sometimes you get a lot. The deeper you go, the harder it is to keep the water out.

I'm not sure if it was used in submarines, but lignum vitae was popular for packing rings. It's a very dense, very hard wood. Even with oil forced into the packing, you're still going to qet quite bit of friction.

On a larger scale, it's the same principle that's used to keep the water from shooting out the top of a faucet when you turn it on.
