How to start in AI: PyTorch, Tensor flow? Or something else?

Hello everyone, I’m currently studying Mechatronics and Robotics in my third year. I have learned the basic principle of AI and learned how to use Matlab to train Neural Networks, create genetic algorithms and Fuzzy controllers. I have also used openCV. I have a decent programming background in Python. I’m really interested in AI and robotics and would love to peruse it as a career. Can someone point me on the right path to learn ML and DL. I’m thinking of learning how to use Tensor Flow 2 or PyTorch. Is this the right way to start? And what should be the end goal I’m working towards? In other words, what should I learn to be competent.
