Yes, as you read. Did you know that you can do Machine Learning with a language that it is not Python? You CAN! And actually companies do this a lot of time... If they need to integrate an AI solution into their workflow built on for example C++ or C#, they need to build sometimes in those languages! If you need to build something that scales good and has very good performance, you might as well need to use a language that it is not Python.
I had to do this myself in my previous company, and I just loved it so much that I staarted a series of it on YT, check it out if you are interested!
p.S: you can also build ML models in Python en train in C++ for example! How cool?
