You're probably thinking of a case where both are being done by the same code, but the jobs are quite different.

AJAX is about communicating between the client (browser) and the server. Sending a request, getting a response, and then doing something with the response. This final step might involve making page changes, but it doesn't need to.

DOM manipulation is about changing what is being displayed on the page: adding, removing, or re-arranging elements and/or giving them different properties. This could all be done based on a server communication, but it also could very likely be directly in response to user interaction and handled entirely in the browser.
