After it took Sony way too long to get PS3 sales profitable, they said "no more" and made sure PS4 and PS5 sales were profitable within a year of release, just like the PS1 and PS2 were.
Xbox is sold "at a loss" only because Microsoft is still accounting for the massive cost incurred by RRoD failures, not that they're losing money per-unit.
Nintendo only ever sold the Wii U and 3DS at a loss for any real amount of time (and the Virtual Boy was a money pit if you count that.)
So yeah, that's basically only true for the 7th gen consoles, because the PS3 was overdesigned and Microsoft was willing to spend money like water to break into the market, then not sour their lead because of RRoDs.
