Decimal odds
Total return is stake multiplied by decimal odds, including the original stake. A $10 stake at 2.50 returns $25 if it wins, for $15 profit.
Implied probability
Divide 1 by decimal odds. Odds of 2.00 imply 50%; odds of 1.50 imply about 66.7%. This is the probability implied by the price, not a forecast.
Understand the margin
For a two-outcome market with both sides priced at 1.91, implied probabilities sum to about 104.7%. The excess over 100% is the overround. It is not a guaranteed realized profit for the bookmaker.
