To clarify, what does the end-to-end encryption in WhatsApp mean? It is one of the security strategies which allows the sender and the intended recipient(s) of the message to have access to the sensitive information. This implies that WhatsApp cannot read the messages neither it can stop this feature as it's enabled to all the users by design.
In the term of how it runs, the other device can be used to encrypt messages prior to sending them. This is where the end-to-end encryption kicks in by scrambling the data into an unreadable format called cipher text for it to be transported to WhatsApp's servers. The cipher text is then delivered to the recipient's device and decrypted for viewing. It means that these messages cannot be read by anyone else because they are encrypted and transmitted through an inaccessible platform.
