Don't be put off by the laundry list of skills posted on job listings. Most of what they want will be superficial or if it is very detailed and critical it is VERY unlikely they would cut the new guy lose on it. I would say focus on Python, AWS/Azure. Most companies don't have a clue what they are doing with ML or AI so they are just chasing a fad. By all means bone up on it in your spare time but don't let it put you off from applying.
