Can Popes just make up rules?

Even though the bible is true, it does not contain everything. It says that we need to follow the traditions.

The earliest author to talk of the Seven [or Eight] Capital [or Deadly] Sins, is John Cassian in the fifth century, in his Conferences. The whole idea was originally monastic.​

The present list of seven, is no older than Gregory the Great, IIRC. It was a convenient and handy way of thinking about sin that “caught on”. ##
