not necessarily, 50-100 person team in random bank for example can’t even do all of the tickets they should in whatever timeframe they have less alone refactor something properly, and not cos they are busy, but for variety of other reasons, one of them being turnover. this has a lot to do with how your code looks to begin with, bad code is generally hard to refactor, and refactoring is not a cure for bad code.
