When two sentences are separated by only a comma, this is called a "comma splice", and it is not correct. The correct punctuation is either a semicolon instead of a comma, or to keep the two as separate sentences, each ending in a period.
Examples
Comma splice, incorrect: Carla studied Spanish, Peter studied German.
Semicolon, correct: Carla studied Spanish; Peter studied German.
Two sentences, correct: Carla studied Spanish. Peter studied German.
You can also use a coordinating conjunction like "and" to "fix" a comma splice:
Carla studied Spanish, and Peter studied German.
Note: A similar punctuation error in which two sentences are joined together with no punctuation between them is called a run-on sentence:
Carla studied Spanish Peter studied German.
A comma is a punctuation mark used to separate elements in a sentence, like words, phrases, or clauses. It helps to clarify the structure of a sentence and improve readability.

It's called a run-on comma splice.
If it is possible to replace a comma in a given sentence with a period, and wind up with two sentences that are each complete and that make sense as sentences, then the comma that you replaced was being used to splice together two sentences. This is generally a bad idea.
