Transfer RNA refresher

A different discussion piqued my curiosity, so a question for anyone with familiarity, as my own study in this is decades old…

The correspondence of the various transfer RNA molecules, wherein one side (the anticodon) will only correspond to certain codon combinations, and the other side will only attach to particular amino acids…

Do I recall correctly that the correspondence in these various tRNA molecules which creates the genetic code is entirely arbitrary within each tRNA molecule?

That is, there is no chemical reason that a certain tRNA molecule that corresponds to the G-G-X codon ought to attach to glycine on the other side of the molecule, rather that this correspondence is simply built into that molecule and all other relevant tRNAs?
