Earlier quoted context omitted.
Loneliness sucks, and for some people it can be difficult to try to meet new people in “real-world” social interactions.
I'm one of those people, but dating apps only ever made things worse. I can't imagine why anyone would want to use them unless they literally could not live with being alone. Fortunately for me I have decades of experience at that.
I'll tell you why: Why be content only meeting the subset of women I can meet face-to-face in my free time when I can complement my social life with a dating app that helps me meet more?
I can do both.
I can only understand your confusion if you have zero success on dating apps and assume nobody else has any success, either. And there are people obviously having success on dating apps.
