It's not like the Fool's Journey in Tarot. It's a bingo game that we're taking and re-purposing as a divination tool. The printers don't care about non-game use. As Loteria became an established part of Mexican culture and more popular other producers made various versions of Loteria cards with certain themes.
Loteria has been played as a game of chance, as a pastime, and for educational purposes. Because the Loteria cards include the name of the pictured character, they are used to teach reading, writing, history, and social values. Many bilingual teachers use the game as a teaching tool in the United States.
