I’m trying to figure out if gravitational fields and gravity interactions can produces the same results as space curves to cause gravitational attraction.
You'll have to define "gravitational fields", "gravity interactions" and "space curves" for me, since I'm not quite sure what you're asking.
The Newtonian picture of gravity uses gravitational fields to describe gravitational attraction, and it works fine in a lot of circumstances. The general relativistic picture of gravity uses curved spacetime to describe gravitational attraction, and it works even better.
