false

Vos (the "voseo") is used as the main form of the second person of the singular you in the River Plate Spanish of Argentina, Uruguay and eastern Bolivia, and in the Paraguay's spanish.

It should be noted that the "voseo" is a linguistic phenomenon within the Spanish (castilian) language in which the pronoun "vos" is used along with certain particular verb conjugations instead of using the pronoun "tú" in situations of familiarity.

Specifically, "vos" is extended throughout Argentina, Uruguay, Paraguay, Costa Rica, and in some regions of: Bolivia, Chile, Peru, Ecuador, Colombia, Venezuela, Panama, Nicaragua, Honduras, El Salvador, Guatemala, Mexico and Cuba.

Nevertheless, this is not used in all the countries of Latin America or  all its regions.

Therefore, "voseo" is not used in all Spanish-speaking countries.
