How common/rare is winning literally the FIRST EVER RUN, when you install the game?

Of course I have SOME knowledge of STS (A5 I think was the most I got up to) and finally bought STS on PC.

I know the first run is supposed to teach you the basics, but how common is it,, that you literally win your FIRST EVER run as LVL1 Ironclad?

Not flexing or anything, just wondering, because you get stronger as you level up and I dont think youre supposed to win your first run..?
