Every enterprise is already using serverless applications in some form or another

If you have an application that makes a call to an external application, then you're on the calling side of a serverless application. Here's a high level graphic to illustrate my point:
You essentially have no insight into how the Results are generated by the "cloud" you're accessing via IP address or hostname. So you're accessing a service, but the actual server part of that interaction is abstracted from you.

Here's a great article on the concept of "Servicefull Serverless" to go into more detail about this:

Now, the current definition of "serverless" leverages all kinds of possible technologies like AWS Lambda or Whisk or even Cloudflare Isolates, on top of containers and Kubernetes running in VMs (or bare iron in the case of Isolates). So it's extremely important for you to understand those components at some point, but from your view as a consumer, you're already using serverless technology.
