Implied probability, % — 1 / decimal odds. This is the price the bookmaker set, not the "true" probability.

The implied probabilities of all outcomes sum to more than 100% — the difference is the bookmaker’s margin.

The converter changes the notation, not the substance: odds in any format contain the bookmaker’s commission. Verify calculations yourself.
