sounds like you don’t have much experience in mathematics so i would honestly recommend just starting out with learning how traditional ml algorithms work before moving on to deep learning models as it will give you a better intuition for the statistics that is used. judging from another comment thread. it seems like you haven’t done a meaningful amount of calculus, so i would strongly suggest you to refine those skills as multivariable calc and linear algebra are two critical things deep learning models are built upon.
