Decimal odds are converted to implied probability as 1 ÷ decimal odds. Real market prices may include margin, commission, liquidity effects, and delays, so this value is not a model prediction or a guarantee.
It is the probability implied by an odds price before accounting for market margin and other costs.
No. It is a conversion of a price, not a claim about what will happen.
