The "theorem", if we wanna call it that, says that, given an infinite amount of monkeys and time, they could write Shakespeare.
This doesn't mean it's actually possible in the real world, it's just to say that random events can seem, from the outside, like intelligent creations. Like a cloud that looks like a pig, no one actually created it to look like that, it was just random happenstance.
I'm pretty sure that, with autocorrect, it's harder to write sm than some, so idk ¯\_(ツ)_/¯
