Yes, the first sentence is in the present perfect tense (to have + past participle verb) and implies that you have finished learning and there is no more learning to do. The second sentence is the present perfect continuous tense ( to have + to be pp + verb-ing). "I have been learning" implies that the action is ongoing and you are continuing in your studies. I hope this helps :)

The first sentence suggests that you now know French and have completed studying. The second says that you are still learning French and are referring to study time that you have completed until now. I hope that helps.
