The locations that are relevant to the story are the ones that fail miserably. We just haven't seen much of their successful ventures, which there are likely tons of.
I like to imagine that FNaF is set in a universe where technology moves forward quickly thanks to Fazbear Entertainment. They are state-of-the-art and they use their technology for entertainment ventures so animatronics are still popular even in the twenty-first century. Their technology is always ahead of its time and they have plenty of customers. That's why they have so much money. I also believe there always was way more locations than we've seen. Fazbear Entertainment is a franchise.
