Resistance training will lead to weight loss by itself if that is all that you do and by weight you are referring to bodyfat weight.
Cardio training will lead to bodyfat loss if you do heart rate interval training. Yes, you will also lose some bodyfat if you just do long cardio sessions like most who just jump on those machines in the gym, set the machine to “fat burning zone” but mostly you’ll just burn up the calories eaten that day, some fat, and eventually muscle and look like on the scale you’ve lost fat when indeed you may’ve lost precious muscle.
Yes, resistance training and cardio interval training together will cause a person to become a metabolic efficient calorie burning machine while at rest.
Getting your body to burn while at rest is what you want so that you are always burning fat for fuel, the preferred source of fuel by the brain and heart and most other tissues contrary to popular belief.
