How many lessons does it take to become a pianist?

That's kind of like that philosophical question..."If a tree falls in a forest and no one is around to hear it, does it make a sound?"

Is becoming a pianist a matter of lessons or a matter of attitude and effort?  Or just taking the action to press the keys?

Do you need the label to play?

Can you just play?  For fun?  For sound?  For release?  For yourself?

Are you a pianist if you play for yourself?

Maybe it's a matter of self-confidence and if you think you are then you are.

Maybe.
