I'm playing on a vanilla Minecraft survival server, and have been trying to get Mending books by fishing. It turns out that I've only gotten one book in about a week of play, and it was Fortune II. This is weird, because my rod is Lure III, Luck of the Sea III, Unbreaking III, Mending, basically the best you can get, and I've been fishing for a very very long time.
I've thought about Lure having something to do with it, after all, it decreased the chances of finding treasure to find more fish in earlier versions, but my question is, does it still happen now, or am I just unlucky?

According to Minecrafts Gamepedia Enchanting page, Lure only increases how often the fishing rod will catch something:
Meanwhile Luck of the Sea increases chances of treasure:
So to answer the question, I really see no reason as to why Lure would counter the effects of Luck of the Sea. I think you are just really unlucky.
Note: According to a table on an almost duplicate post on Reddit, your chances of catching treasure are still at a low 11.34% (though much better than the standard 5%).
