Yes, that's totally fair. But I'll say that I've taken or been offered "networking-enhanced" job opportunities in startups a handful of times, and they were always people I knew and had worked with directly, or in one case, someone who was extremely close to a person I had worked with directly.
"Chatted with someone at a networking event" seems like an extremely weak signal, and I'd be suspicious of that type of hire.
