That's correct. Startups, freelancers, side-hustlers. In short, people that just want a nice logo, but don't have the budget and / or time to work with a professional design agency. Regarding mathematics and aesthetics: whenever you generate something with an algorithm, you'll inevitably give up some kind of variation. An algorithm only works within a subset of all possibilities. So I don't think logo generators can do everything that a designer can. But for a lot of people it's the perfect option. You'll get a good logo for a friendly price.
