DJI RS4 Stabilization Help

hey ive been practicing with the rs4 pro and I have been trying to get really stable shots, but theres always that shake and I need help on what i can do about it. i seen other creator videos with the same equipment I have and its extremely stable. I want to be able to recreate that. Ignore the last bit, im more focused on the walk down the hallway for now. I am going to do real estate videgography and I want to first start with getting my footage stable because I have been struggling on that for a really long time
