Longer focal length, more zoom, more perspective compression, more blur outside of the focus area.
Wider open arperture, more light on the sensor, more blur outside of the focus area.
Longer exposure time, more light on the sensor, more motion blur.
Bigger sensor sensitivity (ISO), more light collected per unit of time, more grain/noise.
Bigger sensor, bigger field of view, more blur outside of the area of focus.
Then you also have neutral density filters (ND filters), which allow you to modify the exposure time/aperture while keeping the ISO where it is (e.g. if you wanna blur the background in bright sunlight).
You become a good fotographer if these interconnections are so well understood you don't need to think about them anymore — and you can focus your effort on finding the right combination of camera position, angle and lense settings.
The position and angle is what makes and breaks a good picture. This is why a good photographer with a smartphone takes better pictures than an amateur with a Hasselblad.

Much like any skill: music, computer programming, cooking, etc. Mastering the technical fundamentals liberates you from having to worry about the technical fundamentals.
