I don’t think one way or another, intentional or non-intentional, I’m more concerned with the end user experience and wish they would just make it truly random.

It will always be 'Pseudo-Random', no matter what they try to do because computers just can't do 'truly' random numbers. Bungie can, however, identify the spread and reorganise their loot and perk tables to align their 'common' drops to the most common results and their 'rare' drops to the rare ones. Time consuming, but definitely 'do-able'

Computers can’t truly do random numbers?

Nope. They use Psuedo Random Number Generation (PRNG). You essentially use a 'seed variable' and generate all of your numbers based on that, and with enough iterations you'll start to see a pattern form where certain numbers in the spread are generated more than others. In games that use 'random' loot tables, developers put the most common gear in the table positions that are referenced most and the rare gear in those that barely get referenced at all. It's why most games that use loot tables can quote the odds of certain gear dropping.
