Not necessarily. What's to say that you're not experiencing the robot's "memories" right now?

Like your whole life is (for lack of a better way of describing it) building up to being the consciousness that "lives on" in the robot?

If that's the case, you'd think you "got lucky" and woke up as the robot.

There still would 100% be a poor sap that was left as a mere mortal /dead.

In that case, it absolutely is 50/50 you "end up" as the robot or mortal / dead.

Exactly. Though it's not QUITE as easy.

Theoretically the copy would think it's "you" also.

So you essentially have a 50/50 chance of waking up as the robot or as the poor sap who's still mortal or (worst case) now dead.

Of all things, the movie "Multiplicity" deals with this pretty well.

Same with that Black Mirror episode with Jon Hamm.

So the real question you have to ask yourself:

"Do you feel lucky?"
