Uninstalled package but command remained usable as user (command not found with sudo)

I recently installed silversearcher-ag with sudo and uninstalled it as it required sudo to run the command every single time. The command I used to install and uninstall this package respectively:

# installation
sudo apt install silversearcher-ag

# uninstallation
sudo apt remove silversearcher-ag
sudo apt autoremove

As mentioned by the comment, here's the output for type -a ag: ag is aliased to `apt-get update;apt-get dist-upgrade' After uninstallation, I found that if I do sudo ag, the command would correctly fail due to command not found; however, if I simply do a ag as user, I was still able to run the command ( although the command actually failed due to lack of permission, i.e., it has to be run with sudo every single time). I've looked at places like /usr/bin/, /usr/local/bin, /usr/sbin/, /usr/local/sbin, sbin/, bin/, the ag command didn't reside in any of them. whereis, locate returned no matching results. I've also tried sudo apt purge silversearcher-ag sudo apt purge silversearcher-ag* The first command actually removed some additional affliations, the second simply removed none. After these two commands the ag was still there. What do I need to do to completely remove this package? I am running MX Linux 23-ahs, based on Debian 12 bookworm.
