Deleting a photo album does not necessarily delete the photos stored in it. When you delete an album, the photos within it may still be present in other albums or in the "Camera Roll" or "Photos" section of your device. To completely remove photos, you need to delete them individually or select and delete them in bulk from their respective albums or from the "Camera Roll"/"Photos" gallery. It is important to note that once you delete photos from your device, they may not be recoverable, so caution should be exercised when deleting any important or sentimental images.
