Gold trading is profitable only when expectancy is positive after costs: (win rate multiplied by average win) minus (loss rate multiplied by average loss) minus costs.
Break-even win rates are about 50% at 1:1 reward to risk, 33% at 2:1 and 25% at 3:1. Most gold accounts lose because of FX-sized positions on a metal, stops set inside gold's noise, trading through US data releases, regime blindness and judging a setup on ten trades instead of a few hundred.
