To hopefully give some encouragement: you can for sure play all modern games on a game controller with only a single hand, but it might take time to learn how to do so. There is a speed runner (who holds at least one world record) that has a disability preventing him from using more than one hand when gaming, and he regularly used modern controllers. You can see his Twitter here: https://mobile.twitter.com/halfcoordinated https://mobile.twitter.com/halfcoordinated and can easily look up recordings of him playing (with a camera focused on his hand) at games done quick. I recommend his Vanquish run.
