sometimes I think if you look at the amount of token supply in such a large amount that trillions and trillions after the project runs several months or years, the token will be burned, what for if you make tokens with a large supply, but will be burned, ...?

This is a kind of strategy by some project they put a large token supply then hold a huge amount after several months or years they will burn supply to increase the price because people think burning supply will have a chance to increase the price this will serve also as a hype.
