Does 32GB RAM help a lot for Blender rendering?

Yes, if you’re working on large 3D rendering projects in Blender, 32GB makes a noticeable difference over 16GB. Complex scenes with high-poly models, multiple 4K textures, or lots of particles can easily chew through 16GB, causing swapping, laggy viewports, and crashes. 16GB is fine for small projects, but for serious rendering, 32GB is the sweet spot.
