I hate to be discouraging. I wanted to do the same up until these interactions. Depending on what is a livable wage for you, or if you're doing it on the side, it could still be possible. But I'm in high cost of living areas in the US and it seems totally unfathomable to me. I watched companies spend literal millions of dollars on just advertising to gauge interest in games they then shut down because they couldn't make the game profitable enough to pay for the ads and their bills etc.
There are definitely success stories, and you can definitely get games released and get players. But I just want to point out that many of the games are simple and just have absolutely astronomical amounts of money behind them. Mobile is fucking crazy and I feel like it's much harder for smaller devs to get their name out through typical advertising channels.
IMO, which is mostly just guessing based off what I've seen, I'd think your time is better spent finding small communities that may be interested in your game and posting about them, as opposed to buying ads etc. Indie dev subreddits and other gaming communities have propped up successful games before, and it may cost you more time and effort, but it just looks extremely hard to compete on the mobile ads playing fields against these huge companies these days.
