UK unis are much more quantitative in their admissions than those in the US. For most, if you meet their stated typical offer, and have a decent LoR & PS (essay on why this subject) a US student is likely to be admitted.* They don’t care if you love them- and they won’t pretend to love you either.
*There are obvious exceptions: St Andrews cares more about GPA than pretty much any other UK uni, and. Oxford, Cambridge, Imperial and LSE are tough admits.
