Theory of Games

No. 1st-Level PCs were always experienced in their fields, making them a step above the typical warrior, cut-purse, scholar or priest.This isn't the only example, but it's one of the best, as it posits your 1st-level Fighter is actually a veteran soldier with extensive military experience, a far cry from "a kid fresh off the farm who decided to go adventuring"!
So is this the moment where the definition of what a low-level character is changed?
But 1st-Level PCs have and will always be trash. Like "I was born to fail" TRASH. They only survive due to sheer luck and the tender mercies of GMs. The most casual combat encounter and they get blown out like a birthday candle.

Total ZEROES especially compared to a 5th-Level PC. 5th-Level is the beginning of Heroism. It's when your PC has real capability. That's in pretty much any ttrpg that has levels.
