If you sell a lot, Valve will reduce their cut on Steam to 15% IIRC. And Steam keys are free to developers - that is, you can generate Steam keys on your website and sell them and Valve gets nothing in return, and there's no volume requirement like there is for reducing Valve's cut on the Steam store.
Steam also doesn't do exclusives (beyond Valve's own titles), nor do they pay any OEMs to pre-install Steam - with the exception of the Steam Deck, all Steam installs come from people who actively seek them out. It's not like Apple where (until recently) you had to go through them to get your app on iOS and pay them every step of the way for the privilege.
