Likes are what turn into stars, though the system is a bit weird imo.You need 25 votes to get any rating, and ratings start a 3 stars. As an item gets more upvotes, it will get 4 or 5 stars.

Items with 2 or 1 star have received a significant amount of downvotes to reach those rankings. Only few items have this and are usually things that break your game.

And anything with less than 25 votes will have no star ranking.
