if you go to the premium section and look at the benefits it literally says (from memory) if you pay 3.5€/month you get a small boost on interactions for your tweets. If you pay 5€/month you get a bigger boost on interactions if you pay (I don't remember how much it is) 22€/month ~ you get the biggest boost for your tweets.
That to me sounds like if you don't pay, you're going to be in the bottom of the feed for everyone else.
