Exactly. The risk is not eliminated, you choose which one to take.
Saving on FIAT is choosing the mathematical certainty of devaluation. Saving in gold or Bitcoin is choosing volatility in the short term, but protection in the long term.
The real question is not 'Which is risk-free?', but 'Which risk do you prefer: guaranteed slow erosion or volatility with the possibility of growth?' For me, the choice is obvious.
