Difference between `bazzite` and `bazzite-deck`?

I see many YouTubers showcase bazzite but it seems like it’s always bazzite-deck image they are showing.
Are the YouTubers wrong in this case?

bazzite-deck is configured to give a SteamOS-like user experience via the Gaming Mode/Steam Big Picture, as opposed to the regular bazzite image that provides a more traditional Linux desktop experience.
