Do I really have to download the Dev Kit through steam AND Unreal?

So I finished downloading the Dev Kit on steam, click to run it and it says download the Unreal Launcher. Ok, fair enough. But apparently it requires another 60 gigabytes of download after the 37.4 I just did? It doesn’t seem right to me. Can anyone clarify, or tell me how to link the steam download of the Dev Kit to the Unreal launcher? Thanks, sorry for posting so much.

no just off the epic launcher

What. What is the download on steam doing then, with 37.4 gigs of download?

the old devkit

THe dev kit that has not been updated in something like a year.
