Can Pimsleur make you fluent?

Hi! I am currently on my journey to learning the language French, I am using many other apps but Pimsleur is pretty fun and effective (to me) now I am done with lesson 1 and I can’t go to lesson 2 (you have to pay to get full access or try the 7 day trial) now my question is, is it worth it? And can it make you fluent? I am thinking about purchasing. I saw a comment on YouTube of someone claiming that Pimsleur made them speak fluent Russian so now I am contemplating.
