Virtual machine allows users to run programs from different operating systems simultaneously

Yes, that is correct. A virtual machine (VM) is a software implementation of a computer that allows users to run programs as if they were running on a separate physical machine. This allows multiple operating systems to run on the same physical hardware, and enables users to run programs that are not compatible with their host operating system. This is done by creating a virtualized environment on the host machine, where the guest operating system can be installed and run as if it were on its own physical machine.
