What is the difference between Latino/hispanic people and Creole people?

Hispanics and Latinos are an ethnolinguistic group of Americans with genealogical origins in the countries of Latin America and Spain. More generally it includes all persons in the United States who self-identify as Hispanic or Latino.
Hispanic and Latinos are racially diverse, although predominantly white or mestizo. Mestizo is not a race but it is a person who has both White and American Indian ancestry.
As a result of their racial diversity, Hispanics form an ethnicity sharing a language (Spanish) and cultural heritage, rather than a race.
American Hispanics are predominantly of Mexican, Puerto Rican, Salvadoran and Cuban ancestry.

The term Creole and its cognates in other languages, such as crioulo, criollo, creolo, kriolu, kreyol, kreol, kriol, etc. These have been applied to people in different countries and epochs, with rather different meanings.

But I think you were probably asking about these;

The Louisiana Creole people are those who are descended from the colonial settlers of Louisiana, especially those of French, Spanish, and African descent. The term creole was first used by French settlers to distinguish between locally-born, mixed-race slaves and those born in Africa, when they were recording slave inventories.

It was a term used for "native-born".
The most precise current definition of a creole is a person of non-American ancestry, whether African or European, who was born in the Americas.

Louisiana Creoles have common European heritage and share cultural ties, such as the traditional use of the French language and the continuing practice of Catholicism.
Some Creole people have African and/or Native American ancestry.
