Understanding odds formats:
- 🧮 Fractional (e.g. 2/1) — used in the UK: indicates profit per unit staked.
- 📐 Decimal (e.g. 3.00) — used in Europe: indicates total return (profit + stake).
- 🇺🇸 American (Moneyline) — positive = profit on $100 stake; negative = stake required to win $100.
- 🎯 Implied probability — the estimated chance of an event occurring based on the odds.
