Unfortunately, most code out there is using calls to cuda explicitly rather then checking the GPU type you have and using that. You can fix this yourself, (I use an m1 macbook pro for ML and it is quite powerful) but you need to know what you're doing and it's just more work. You might also run into situations where things are not fully implemented in Metal Performance Shaders (the mac equivalent to cuda), but Apple does put a lot of resources into making this better
