Equal RTP does not mean equal variability
Two payout distributions can share an average while producing very different short-term outcomes.
The distinction that matters
An expectation summarises the weighted average of possible returns. It does not describe how far outcomes spread around that average. To calculate variance, you need the payout distribution and its probabilities; a vague volatility label alone is insufficient for a numerical risk estimate.
A worked example
Compare a fictional C$1 model that always returns C$0.90 with one that returns C$9 with probability 0.1 and zero otherwise. Both average C$0.90, but the first has no variation and the second has substantial variation. This deliberately simplified example isolates the distinction without claiming either is a real casino game.
Your next steps
- Keep average return and variability in separate fields.
- Ask what a volatility label measures.
- Avoid assigning numeric variance from an unexplained label.
- Read distribution assumptions before using a risk calculation.
Where this answer stops
An equal long-run average does not imply equal personal results or a guaranteed recovery path. This explanation cannot estimate the chance of losing a particular balance without a complete, applicable model.
