First, a creature can have more than one type. A Human Wizard is both Human and Wizard.
Second, as you'd expect, some tribes are far more prevalent (meaning far more creature cards of that type have been printed over the years). And many types (97, to be exact) are rarely seen, with 10 or fewer different ones of that type printed. In fact, 24 of that 97 had 0 cards printed- these are creature types that are tokens created by other creature types (example: see Nadir Kraken below. Its ability can create Tentacle creatures- a creature type that has yet to be printed as a stand-alone card).
