You own your photos. You own your work. The photos are somewhere on your hard disk, unchanged and unmodified by Lightroom Classic. Your edits are still available inside LrC after the subscription ends. LrC will still launch and allow you to continue to use 100% of the Library Module after the subscription ends so you can access you edits, and export files or print the photos.

From https://helpx.adobe.com/lightroom-classic/faq.html:

"Lightroom Classic on desktop will continue to launch and allow access to your files after your membership ends. However, the Develop and Map modules are disabled. Also, after your membership ends, synchronization with Lightroom on mobile devices will no longer function."
