Tell me about the position on the court that the jersey number generally represents.

In football matches, it is an international practice for teams to print numbers on players' clothes as the symbol of players. At first, it was not to identify athletes, but to mark their position on the field. 1938+0933 FA Cup, using numbered jerseys for the first time. 1938+0939 stipulates that athletes must wear numbered clothes when competing, and each number represents their position on the field (2 3 5 system): 65433. No.2 right-back, No.3 left-back, No.4 right-forward, No.5 centre-back, No.6 left-forward, No.7 right-wing, No.8 center, 10 left-wing,1/left-wing. Later, it was properly adjusted in the 4-3-3 formation, but the number was still 1658.

Of course, this rule no longer exists. You can wear any number of jerseys anywhere in the World Cup, as long as the number is within the 23rd.
