New player questions

Where does one find solo rpgs easily? I’m very new, I recently just got my first two games but only discovered this entire genre from a Facebook ad for a site called Tabletop Bookshelf. When I google to find more sites my search usually just brings up rot video games. On top of that I still have zero idea what oracles are and have trouble identifying what the playstyle of games are( journaling/map making/ etc).
