Each time I call up list-package and update, I get this message after the updates

Operation finished.  Packages that are no longer needed: 43.  Type ‘M-x package-autoremove’ to remove them

Below is my init.el concerning use-package

(require 'package)
(setq package-enable-at-startup nil)

(setq package-archives '(("ELPA"  . "http://tromey.com/elpa/")
("gnu"   . "http://elpa.gnu.org/packages/")
("melpa" . "https://melpa.org/packages/")
("org"   . "https://orgmode.org/elpa/")))

(package-initialize)

;;; Bootstrapping use-package, i.e., if use-package isn't installed
;;; then install it
(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

;;;This will ensure all packages are installed if not already
(require 'use-package-ensure)
(setq use-package-always-ensure t)

;;;This will make sure packages are updated
(use-package auto-package-update
  :config
  (setq auto-package-update-delete-old-versions t)
  (setq auto-package-update-interval 1)
  (setq auto-package-update-hide-results t)
  (auto-package-update-maybe))


I obviously don't want to uninstall all the packages on my system. What have I done wrong? Can you critique my setup here?
