Hello, if I were interested in buying a bundle of games that all have steam keys from the same developer, but on the bundle itself it doesn't say its DRM Free or Steam Keys included in the bundle. Would I get all of the steam keys from buying the bundle or just the drm files? I am more interested in adding to my steam collection which is why I'm asking

I'd ask the dev first but I'd be inclined to steer clear of steam as it's slowly dying off and more Devs are turn to indie aside from the AAA studios of course. Steam has about 5 years left before its end of life unless you are prepared to upgrade your PC regularly. The steam client will only support windows 10 for a couple more years and 32bit Intel Mac operating systems have 2 years maximum. Grow an itch.io library and enjoy your games indefinitely
