game dev why does it always tell me to focus the team

It would be extremely irresponsible not to very strongly discourage you from trying to do this. If you make the equivalent of a minimum wage job you would be doing very well. It's really important for you to understand that solo developing will not likely ever bring you financial success. The skills you learn as a PC developer are also more easily transferable into various other computer/software careers, so that’s something to think about too. Mobile games are targeted towards casual gamers, PC is a bit broader, which means it’s more viable to cultivate a community for your game. The PC market is also saturated, but not to nearly the same extent.

Unless you’re incredibly lucky your mobile game isn’t likely to become a big hit.

They also churn out these games at an incredibly rapid rate, something you won’t be able to compete with. You’re competing with the marketing budgets of these big companies. Then they take that game and clone it, throw the clones at the market.

Mobile game development companies produce hundreds of apps, throw them at the market, and see what sticks. You’ll likely have more success as a solo indie dev with PC. You can work really hard and be consistent, produce amazing games, but get no traction and sales. First things first, indie game dev is not a financially stable investment.
