That is incorrect. There were in fact two 2018 MacBook Pros. A MacBookPro15,2 with a 13" screen and a MacBookPro15,1 or 15.3 with a 15" screen. Both were shipped with High Sierra 10.13.6.
There is a 2019 MacBookPro15,2 13" and a 2019 MacBookPro15,1 and 15,3 15". Both ship with Mojave.

You may not install an operating system older than what shipped with the Mac. In your case, and for a 2019 model, that will be Mojave 10.14.5.
What version of macOS came originally installed when you got it.
That is the oldest macOS version than can be installed
installing hs on a macbook 2018 that was shipped with mojave was succrssful

There was NO MacBook 2018. Your unit is it a Retina MacBook 12 inch?
The last MacBook before Apple Discontinued it was 2017.
Therefore, you made have been successful installing HS
