It largely depends on how you set up your environment. On my home server, most VMs consist of a few gigabytes of a base Linux system and then a couple of hundred megabytes of application code. Some of those VMs also store large amounts of data, but most of that data could be stored in something like a dedicated minio server and maybe a dedicated database server. I could probably get rid of a huge chunk of my used storage if I switched to a deduplicating system (but I have plenty of storage so I don't really need to). If you're selling VMs to customers then there's probably no advantage in using deduplication.
