This is not a bare-metal vs Cloud comparison, the Cuber PaaS is supposed to run on anything including cloud based on their docs. So when they say "save 80% on cloud costs" I am assuming they mean for eg. save 80% on using Cuber on GCP compared to deploying same workload on GKE.
It would be very absurd to claim something like - I was using i9-13900KS but realized I could run the same workload on my raspberry pi, but hey I also used this packaging tool in the process therefore I saved 80% costs because of the packaging tool.
