Bitcoin being able to be divided infinite amounts

I wanted to get peoples opinion on this. Many people ask what’s the difference between being able to divide it infinite amounts and inflation of Fiat currency.

There is a big difference as there will only be a circulating supply of 21 million. With fiat currency the supply is always increasing devaluing the currency.

With Bitcoin, as more people buy in, instead of the price of 1 Bitcoin being 40k the price of for example 0.0002 Bitcoin could be 40k in the future.

Am I correct in saying this? This may be a silly question but interested to hear if this is the right view.
