Mexico's 51% implied probability as Group A frontrunner stems from co-host advantages at high-altitude Estadio Azteca, where they open against South Africa on June 11, bolstered by solid recent friendlies like 0-0 draws versus Portugal and Belgium, plus captain Edson Álvarez's leadership in training camps emphasizing high pressing. Czechia's surge to 24.5% reflects playoff qualification momentum over Denmark in late March and resilient 2-2 draws against Ireland and Denmark, highlighting Tomáš Souček's midfield dominance and defensive solidity. South Korea's dip to 19% follows stumbling friendlies, including 0-4 losses to Ivory Coast and 0-1 to Austria, despite Son Heung-min's threat amid altitude acclimatization efforts. South Africa's 5.7% trails as underdogs, though early Pachuca camps under Hugo Broos aid adaptation for their physical style.
