Cryptography survey as an undergrad
No, I think a general understanding of what a cipher, hash, signature, MAC and a few other of these concepts will make it much easier to understand what cryptography is about.

It's like some knowledge about cars can be very helpful, even if you don't get to be a mechanic. Especially understanding a bit about certificates and PKI is pretty useful, as it is the underlying authentication structure for the internet (especially TLS and therefore HTTPS).

We may be a bit biased here. You can get by pretty well without knowing cryptography. Then again, you won't need a lot of mathematics unless you presume you're going to build cryptographic algorithms or perform cryptographic analysis.
