Automatic_Updater_Disabled Vs.Wp_Auto_Update_Core

I was reading the guide on disabling the auto-update feature in WordPress from here – https://make.www.ads-software.com/core/2013/10/25/the-definitive-guide-to-disabling-auto-updates-in-wordpress-3-7/

I didn’t understand the basic difference between using AUTOMATIC_UPDATER_DISABLED and WP_AUTO_UPDATE_CORE.

From the url above.

3. Disallow the entire automatic updater.

The constant AUTOMATIC_UPDATER_DISABLED can be used to disable the automatic updater entirely. It’s like DISALLOW_FILE_MODS — no changes allowed at all — but it’s specific to the auto updater.

4. Disable only core updates.

The easiest way to manipulate core updates is with the WP_AUTO_UPDATE_CORE constant.

Will using AUTOMATIC_UPDATER_DISABLED disable core updates too?

I know what I am doing.
