Duo lingual vs present tense

I’ve noticed on duo lingo they will translate English verbs ending in -ing to regular present tense verbs in Spanish. Example:

“She is talking” will translate to “Ella habla” instead of “Ella está hablando”

Are they interchangeable? I’ve learned that “Ella habla” would just mean “she speaks/talks”.

I know Duo lingual isn’t 100% accurate, so I just wanted to double check.
