I'm not saying that this exact situation was all hard work. I'm saying that he created the opportunity for interactions and to be noticed through hard work and creativity. There are many notable ways he could have done something with the work he did that would gain some kind of 15 minutes of fame - maybe having nothing to do with acting on a celebrity tweet.
Taken as an exact specific outcome, sure, it's improbable. But across all of the interesting outcomes it's far less improbable.
This reminds me of the argument from Creationists about how we couldn't have been exactly created as we are because the odds of our turning out exactly as we have are insurmountable.
They ignore the success bias of our current outcome and the possibility that many viable evolutionary paths could have led to stable life and even intelligent beings like ourselves.
