You were right in your first paragraph, but this is a pretty bad take.
I didn't buy FF7:R. Know why? PS5 exclusivity and I don't have a PS5.
I didn't buy FF16. Know why? PS5 exclusivity and I don't have a PS5.
See a pattern?
I DID eventually get FF7:R when it came to PC, but mostly because I REALLY needed a diversion from irl around that time and I've long loved the series and world and was invested in it. I have no such ties to 16. I watched a Let's Play and will probably never buy it. I got FF15 on X-Box because I had an X-Box at the time. I got FF13 on an X-Box because I had an X-Box at the time.
SE is going to start losing a lot of money with those PS5 exclusives, and fast. But it's not an excuse. It's a valid comparison.
Even going back a ways, the PS1 was super cheap by the time FF8 and especially FF9 came out. The PS2 had done down in price by the time of FF11 and FF12. A lot of sales counts for them also include literal decades and often ports and remakes into the figures as well. A brand new game exclusive to a single console that had supply chain shortages, is around 2-3x as expensive as its competitors, in a world where many gamers have switched over completely to PC gaming and where the home country of the game release has it as the least owned and least played console? Yeah, that's not an excuse, that's entirely relevant.
And...X, sure, but 12 and 13? lol, no. Those weren't selling systems. FF7, 8, and X have that distinction, but the others likely do not. Not to the level you make it out. I got a PS2 for Kingdom Hearts, not FF12 or FF13, rofl. And know what system I played FF13 on? X-Box. For exactly the reason you mentioned - how overpriced PS3 was.
Let it be known forevermore and throughout the land!
TheNight/Kiros/Titanmen/altarmy has declared that EW (and ShB) are considered universally successful as EW got over 90. ShB he might still wiggle out of since it wasn't "over 90", but EW at 92 is clearly "over 90", and thus "plausibly considered as universally successful".
TheNight has spoken!
