Discrepancies Tutorials and Tutorial Worlds?

Hi, 

I am trying to do the sim tycoon tutorial, accompanied with the world that Meta has set up for it (Sim Tycoon Template). 

However, there seem to be fundamental discrepancies between the content that the tutorial wants to guide through and the actual content in the world. For example (see screenshot showing both a section from the tutorial and the actual script), the tutorial talks about changing variables in the pickaxe "entity" (likely meaning script?) such as miningPower or durability. No such variables exist in the script, the screenshot shows other ones. Similar discrepancies are with the backpack section, maybe more. 

Am I missing something, or perhaps the tutorial was written for a (now outdated) different template version? I'd be happy for any sanity check on whether I am missing something or the tutorial is bunk. 

Thank you so much!
