Why are dating apps so restrictive and expensive?

This absolutely makes no sense. I’m 18 years old and I’ve never had a girlfriend in my life, I’ve been alone for years with no one to play with or even talk to. I’ve tried dating apps but they are either “money restrictive or bot driven”. And this doesn’t help my depression and anxiety because I have no money and can’t go anywhere because of my family and because of the flu.
