All women habe thousands of matches. But there are many more guys than women. So if a woman would have in average a thousand likes in a week a guy would have 100 (1:10 population). But while women have many more likes they can be much more selective, so these 100 guys with likes will be the most attractive ones.

Showing people with less likes would make it more fair, that is right. But the effect will be that a woman will see more „less attractive“ guys and will stop using the app. And women are the users all dating apos have to keep because of the large gender inbalance on dating apps.

I suspect the website optimizes for giving you the most desirable matches first to give you hope that you can match with people like that. Thus it follows some sort of a power law, where the most desirable options get the most matches, and everybody else gets whatever they can get. Yes, there's talk of ELO score, but I haven't seen evidence of that much in practice.
