Yeah, assuming that the cartridge is reasonably good, as counter-intuitive as it is, cartridge is the least important element in turntable set up. I have the impression that many people get it wrong and prematurely upgrade cartridges. Similar things happen with speakers. You have no idea how your speakers can sound until you give them the right signal.
There is nothing "wrong" with picking cartridge as the #1 priority. It can work out great - as it did for me when I added a Koetsu Onyx onto my 1990s SOTA Star. It was probably the most satisfying single upgrade I could have done at that time. There are a million ways to go about analog. Feel free to pick a religious stance on this, but the reality across multiple systems is far more malleable. Same goes for the speakers example.
