Can I use copyright content in my iOS app? Who take the risk Apple or me?

I plan to start a quiz app to help people learn english. I would use a well know dictionary for it. I do not want to use 3rd party free dictionary, because there is a big difference in quality. This dictionary prevent any commercial usage of their dictionary.

Who takes risk after I submitted the app and Apple approved it? Me or Apple?

What if user will upload the content to CloudKit from GUI and not me?

What if phisically I do not store data only always forward the query to their online database, and I only present it?
