Yes, ACF Pro is for adding meta fields to posts. That plugin use in the video seems to be Toolset Types, but you need to try that out first if that is what you need.
You can also try the guide provided here for adding custom post type and utilizing ACF Pro for adding meta fields. Regretfully, this particular customization is outside the scope of our support as this is not related to an issue with the theme.
Thank you for your understanding,
