Are the win rates 'faked' ?

I have thought about the win rates.

With the current situation a lot of people pick the better civs so we end up having matches with good civs playing against good civs a lot and many less games with random vs random civ. This results in making the win rates of those good civs seem less good (because they always face another good civ) than what they would be if all people would play random vs random (then in theory every civ would face each other the same amount of times).

I also feel like civs are not that good balanced like what the win rates are saying but this is only my subjective opinion.

But thinking about this I come to the conclusion that win rates are kinda faked. Or is there something I am missing? What do you think?
