No. They are supposed to be upgraded during OS upgrade. I wanted you to verify that in case you are not running macOS.
Since your CPU model meets the requirements, and your EFI BOOT ROM is up to date. I recommend you to re-verify that your installer media is made correctly. Specifically, the live installer needs to boot in UEFI mode, so one possible mistake is you configured Rufus to make it bootable for BIOS, not UEFI.
Etcher, as recommend by tutorial, has virtually no option to customise, and you’re not likely to make any mistakes. So I recommend you to use that instead of Rufus, if you need to re-burn a Live ISO.

Another possible reason for failure is, you previously installed other bootloaders, e.g. Clover and rEFIt, for other OS that requires BIOS to chain-boot.
