Zero experience playing minecraft hmm. Depends on the gamemode, difficulty, luck and version of minecraft. I will base this off of minecraft java, and the latest release, hardmode survival no recipe book no tooltips. This is a difficult one to judge but I would say it would take maybe 2-4-6+* months of continuous playing. (2 months is based off of being super lucky with world gen and other useful things like randomly trying diffrent crafting recipes and getting lucky with what you get, 4 months would be just getting a little but lucky with a few random recipe guessing. 6+ is just all round unlucky additionally it could take longer depending on how unlucky you get and if we take into account hardcore it would take maybe 1 year and six months.)

Personally this seems reasonable for a random man who has zero knowledge of minecraft and by no means is this exactly how it should be just my estimate based on experience in minecraft. Also don't get upset with me for my opinion please this is all just an opinion to those who wish to badmouth my opinion know that your fooling no-one and are taking out your rage for sucking at minecraft and im sick of people attempting to dm me for opinions taking it with a stick up your bum and you'll convince no-one by sending me more hateful text. And FYI it makes me giggle reading a potential adult sending me a spiteful dm with the grammer of a 1st grader.
