In all honesty, most options will probably be out of reach for someone with lack of experience. For-hire work is one; a lot of smaller studios will do 70% for-hire and 30% in-house projects, but it will take years to build to that level where anyone will trust you with hundreds of not millions of dollars to create a game.

There are mobile publishers that will gladly work with you even with just a few months to a year of experience, provided you can deliver a product. However, the terms will usually be way more favorable for the publisher. What you get though is valuable experience.

"Aside from ads" - be careful not to downplay ad revenue. Many studios live on it. Of course it might be difficult to get enough players without spending a lot of money on User Acquisition, but you just gotta pump more games out.

The reason I mentioned that a game designer is not a "main role" is because they are a luxury that only the more established studios can afford. The kind of design you should be doing is the monetization kind; design your game to generate revenue. This may sound obvious but it's quite involved. There are books on Amazon about the Freemium model that you can read up on.
