I assume from your username that you are from India, in which case I'd recommend you to start finishing all these courses/books before 11th strikes. If you plan to take A-Levels/IBDP you'll have at least some free time to work on projects.
However if you end up studying for NEET/JEE you'll have absolutely no time at all to do anything fun.
Also instead of doing many courses/tutorials try doing projects. Not your generic social media base or restaurant ordering service UI, something that interests you and you want to work on.
That said, CS50x is a great course that doesn't require an extemely large time investment.
I see that you wish to go into AI/ML. Watch 3blue1brown's series on linear algebra, calculus, and deep learning. Learn to love math. You will need a lot of it.
