you can run Windows software on macOS with Crossover Mac which has a free trial and costs between 38-60€.
If that's too expensive for you, you can try running WINE on macOS with the Homebrew package manager.
You can also install Linux on most Macs for free, where you can use Lutris to play nearly all Windows games with no additional cost apart from the game.
If that all doesn't work out for you, you can usually also buy Windows and install it on most Macs. And if even that is not possible, just sell your Mac and get a proper PC ;)
