This question, I think, depends a lot on 1.) How familiar with JS / HTML you are, and 2.) how you define relevant.
jQuery, despite losing a market share to newer libraries like React/Vue/Angular, is still larger and more widespread than all 3 combined. So in that sense it's still very relevant.
That said, after you're comfortable with JS and consider yourself intermediate slowing encroaching on advanced, I think learning one of the other libraries is a great idea because they're very powerful in what they can do compared to jQuery.
Good luck with your journey in self-taught coding!
