I'd be surprised if that is the case—or perhaps we have different definitions of what constitutes a "browser-based application." For example, I do all my online banking in my browser; it's the most fully-featured way to do so. It might not obviously be a PWA or an SPA, but I certainly think it deserves to be called a "browser-based application." What else could it be? It's certainly not a "web page." In fact I'd argue that any site that has content that's scoped to a user and can be manipulated by the user is a "web application."
