From a quick review of the games listed on https://games.skillz.com/popular there are a few that are purely luck-based (Blackout Bingo, Bingo Cash), most that have a very small skill or strategy cap before they’re luck-dominated (multiple Solitaires, Match 3 games, Blackjack, Spades, Bubble popping games, Yahtzee), and a few that seem skill-based (Big Buck Hunter marksman game, Pool, Bowling). Note: without investigating those presumed skill-based games looking for ways they introduce unavoidable randomness, I can’t be sure they really are skill-based.

Conclusion is it seems quite plausible Skillz does offer some partly-skill-based competitive games where you can earn cash by beating other players on your own merits. This isn’t incompatible with their business model - casinos profit on poker despite it being possible to win money at poker because you aren’t playing against the house, you’re playing against each other, and the house is just taking a rake (essentially renting out the dealer and table to the players).
