The limit of my understanding of the fine tuning is along the lines of: we know the engine is running but we don't know how many failed attempts to start it there were. If the conditions hadn't been just right, stars, planets and all the pre-requisites for life might not have come apart and we would not be having this conversation.
The "anthropic priciple" is a step too far, imho, but I think it was written as a riposte to the above, as in: "That's like saying the universe only exists because we are here, to look at it."
I first encountered that idea when I was a kid and thought it ridiculous. I have, since, gained an appreciation that it was a philosophical point: if the universe really was entirely illusory, we would have no way of determining this to be so because all our (equally illusory) measuring equipment could deceive us into thinking it is all real.
