Is 16GB of RAM better than 32GB for gaming?

No. 16GB is not better than 32GB for gaming. The idea that 16GB has lower latency is mostly a myth — if you buy the same speed and timings, 32GB can actually lower latency slightly, but the difference is undetectable. For competitive gaming, 32GB is flat-out better because modern games can push past 16GB easily, causing massive latency spikes from paging to SSD. All else equal, 32GB wins.
