You can build similar muscle mass with body weight strength training as you can with weights

But you must ensure you apply a high intensity of effort by bringing your sets within close proximity to failure (you don’t have to fail)

And you must apply progressive overload

This is technically true, but it’s much, much, much harder to do. Use weights if you can access them. Less risk of injury if used correctly and you can achieve much better results in far less time.
