Ethereum is deflationary?

I read more than once that Eth is turning deflationary once shifting to POS , can someone please explain how can it be deflationary when it has unlimited supply capped at 18 mil eth per year ?
I understand there is a burn but does the burn value exceed the annually created Eth ?
Also , i understand that POS won’t need miners does that mean no more 18 mill eth per year or they will still be created nonetheless and maybe go as a stake rewards to validators ?
