I can prove. DM me for an escrow bet. Would you bet $5k-10k since you are sure? I will rank a new domain website's pages on medium competition kws with backlinks.Just proof it and i will pay you.
Nothing else matters.
There is a secret sauce of backlinks, there has to be active real traffic on them coming to the website by clicking on that anchor/link. This might be what you are missing.
Where does your misinformation come from? Did you buy links everyone buying as they are marked with tons of outbound links and might be marked by Google? Maybe you tried those guest-posting or news sites that is also bloated with unrelated outbound links? Or no traffic websites with high da/dr? That won't work.
