Minecraft: I fished out a rod in Bedrock edition minecraft and I am wondering the odds of this pull

I pulled this out with a unenchanted fishing rod.
My friends didn’t believe me and the ones who did said it is about 1 in a hundred million.
This fishing rod has un breaking 3 Luck of the sea3, mending, and Lure3.
Note: This was before mending2 existed. I beleive that this is the best fishing rod possible at this time. It was pulled up Jan17, 2020. (Bedrock Edition)
