You are correct, but I want to point out that opening the machine or software for public inspection is not the case. Cryptography and End-to-End Verifiable Voting, give you the privilege not to trust anyone with the results, not even the designers of the system, (not because you can see the code, most people won't understand what it does anyway) and even if you don’t know anything about software you can always find a professional of your choice that would do the verification for you (simply write a program that counts the votes and verify zero-knowledge proofs. after the election is over (before it's over the key is unknown) (much alike the way people can choose their own doctors).
