ELI5: Why do Formula 1 drivers need to watch out for the condition of the car over multiple races?

I get that they can't drive how they want and destroy the engine and crash in the last lap.
But then the commentator said that Bottas needed to watch the car for next weeks race. Why can't they overheat (or overuse or whatever it is) their car to gain advantages in the last laps and have their car fixed until next week? Mercedes has enough money to build an entire new race car for next week.

The number of engines and other parts are limited by the regulations. This is exactly to limit the advantage richer teams like Mercedes have over poorer teams.  It’s supposed to make for closer racing.
