The best first step I think is to get a virtual drone simulator. There are free ones online that will give you a taste of how it's like to fly drones and will let you get a taste of what it's like. This alone will take you a long way towards being able to use them practically at virtually zero cost, or maybe at most the cost of purchasing a controller to more closely simulate a drone's controller.
Just look up FPV simulator, racer, or anything similar. There are free ones even on Steam.
