@sezzalovesmj Short answer yes, but it depends.
Long answer: if you're new to training in general, kettlebell swings will likely strengthen your posterior chain and be a big conditioning hit as long as you're doing enough volume.
However, as you get more efficient with the movement, the strength component will slowly become a power/power endurance adaptation, which isnt a bad thing.
As others have mentioned, monostructural cardio like running and biking are preferred over swings due to the ability to tweak the intensity more easily. In particular doing easy cardio (eg Zone 2 cardio) is hard to do with kettlebell swings. Typically your grip strength also becomes a limiting factor for how much volume you can do, even at lower weights.
That being said, from a cardio perspective swings can be a great exercise to improve conditioning at higher intensities (Zone 3-5) which is why you see them in metcons and HIIT workouts, which I think are underappreciated in a training program.
