2800 is not even that many depending on the company size. At my current employer I'd guess we have somewhere between 2-3x that, and those are more complex services than a simple lambda + endpoint in each. Just my user with its groups gives me ownership of some 200+ components.

Those are only backend microservices, not counting data pipelines, and other supporting applications.

What constitutes a microservice is a philosophical question very related to the company's culture, some companies will prefer very small single use-case services, some will develop microservices that support a whole isolated functionality (with business logic) to be re-used across the stack. There's no single definition that can be applicable to such variety of architectures.
