The advice does work, especially for neurodivergent people.
People who are neurodivergent in an uncomfortable situation, will typically deal with or process the bad situation by avoidant behavior (such as avoiding a social situation, or mentally checking out of it by being on their phone and so on), "fake it until you make it" is about trying to progress towards more instances of "suppressive behavior", which is where you try and engage in a situation (physically/mentally) even though it's uncomfortable, and hopefully enjoy yourself or learn a few things.

Avoidant > Suppressive > Reappraisal
It might work for making an autistic person more socially acceptable, but it fucks up their mental health. There's a whole host of negative psychological effects associated with masking.
That's certainly not the type of thing anyone can or should ever fake.
