ELI5: Where does the strength from a hydraulic press come from?

Explaining like you're 5:

It's basically the fluid version of a lever or gears.  You exchange speed for force.

An example: You turn on your kitchen sink faucet, and stick a glass under it.  In a second or two, your glass is full of water, but it's not very heavy.  However, if you stuck a bucket under the faucet and left it for a few minutes, you'd have a really heavy bucket of water because the bucket is wider and deeper.  Now imagine this with the water flowing much faster, and in a closed system so there's a ton of water pressure instead of weight.
