Honestly not that much. The biggest thing Valve brings to the table is advertising and access to customers.
Hosting doesn’t cost that much. If you were that desperate for bandwidth (no one is), torrents exist as an option. Blizzard used to have torrents built into their downloader.
The infrastructure is a nice afterthought.

My day job is designing complex IT platforms.
And the cost goes massive down with size.
So. If your game sells badly, you will most likely spend more. Oney in hosting and distribution then you would make profit.
For example, assume your game has around 50gb. You sell 100 copies of it. You can easily calculate 1-2$ per download.
Add your own personal on top of it, someone has to run that stuff, and licensing and more for statistics tooling and more.
Platforms like valve allow indie devs and small studios to avoid all those costs upfront.
“Not that much” depends on the view
