Why is everyone saying that the Xbox SeriesX is more powerful than the Ps5 in terms of performance, even though the gaming performance doesn't depend on Tflops?
Because it is stronger purely from the raw computing power, that is factually correct for the time being. With a game console, it doesn't just depend on the computing power, then you would just get a PC.
With "all" you lean a little far out of the window.
There are always people who make a claim and firmly believe it, regardless of whether it is correct. You can find similar examples e.g. Even in the automotive world, there are enough people who are still convinced that V-AG vehicles are of high quality.
Another and perhaps closer example would be those who claim a console is better than a PC. That is also not true, but there are enough who are convinced of it and hold on to this conviction.
These are mostly the typical "console war kiddies" who see every difference in numbers as a reason to praise their favorite console in the sky and devalue anything but garbage.
What the respective numbers actually say or how big the difference really is, is completely ignored in most cases.
The main thing is that something is "better" than others.
The difference will probably be quite small. The multiplatform games will probably look a bit better on the XSX, but the loading times are a few seconds longer.
