Correct. And that's what I'm saying. So, download all of your Photos and Videos to your iPhone. If that concerning, then download all of your Photos and Videos as a backup, making sure you have enough of a storage capacity to back them all up. See here: Download iCloud Photos and Videos - Apple Support

Download these First:

No. Not if it is downloaded. If it is not downloaded, however, then, yes, it will be deleted form iCloud. So, along as there is in down-arrow on the bottom-right corner of the photo's icon, then it is downloaded.

Any photo deleted from your iPhone is also deleted from iCloud if syncing is enabled.
