I don't get it. They say they use a dictionary, and they say it works without an Internet connection. How can both things be true? I'm pretty sure there's not, say, a Quechua dictionary on my phone.

It doesn't come with all the languages, you have to download them.

I think it's Android only that you can download the language packs, FYI. The language packs + offline maps are super helpful when travelling abroad.

You can download the language packs on Android and iOS, and each one is about 4 MB in size.

Are you sure?

On my desktop, the english dictionary is ~1 megabyte uncompressed, and compresses to ~250k with gzip. The download for Google Translate is somewhere around 30 megabytes.

You have to download them beforehand, and offline translating is limited to just a few languages.
