Are encryption keys removed when you delete files on an iPhone?

Files on your iPhone are encrypted through the password that locks your iPhone. That encryption doesn't stop unless you turn off the passcode function on your iPhone. Deleting files changes nothing about the iPhone's encryption.

The deleted files are gone. The only time your data on your phone stops being encrypted is if you remove the passcode entirely. Don't do that.

So deleted data is not recoverable even with forensics

What makes you think anyone would try to do that? Do you have trade secrets on your phone? Or plans to influence the 2024 presidential election? Or a map to the treasure of Oak Island?

If this was my goal what’s the chances of them recovering deleted data

If you are attempting to gain access to someone else's valuable data based on the knowledge you seem to have, you're doomed to fail.
