The "cheapness" argument is open to debate. So far the main argument I've seen for Function-as-a-Service offerings is that it's cheaper than just paying for a VM instance to run a dedicated service. To start off, a dedicated VM can cost about 5€ a month, which represents the absolute total saving that is supposed to be driving this discussion. Even if we ignore this fact, if you already have VM instances running somewhere then you certainly have enough computing capacity to spare to run these compute tasks without having to incur in extra charges per function call.

a VM can cost far less then $5 a month to run, depending if your bussiness is large enough and can run (or have it run for you) its infra properly.

I once did some simple estimation of a cost of a VM inside our own infrastructure, and the costs was something around a euro or less.

A single, modern server can hosts a crapton of VM's, especially if you have a competent operations team inside your bussiness who builds tooling for it.
