SpaceX's yearly spending would include the 61 flights, but also literally thousands of satellites, presumably a huge number of commercial dishes, their human flight overheads, their Starship development program including ground support and production and testing of about a hundred Raptor engines, their sales and outreach, their specific contract work like HLS, and their mug business by the side.
If you were to amortize SLS's total dev costs (incl. Orion and SLS-specific ground support but excluding Constellation) over its reasonably expected lifetime flights, you'll be lucky as heck to get <$10B/flight, though of course we don't know how that adds up and so report the much smaller marginal numbers instead.
SLS and Orion are dead ends. I wish them well and I am huge space geek but that program is just a gigantic waste. I wish we could take that budget and use it for unmanned missions or public/private space station partnerships with some of the new space companies.
