Sounds like you just have some learning gaps to fill in and need guidance on how to fill them. Beyond that, I recommend interning or volunteering to gain industry experience and domain expertise (e.g. retail, real estate, healthcare, education, pharma, politics, etc). But first thing's first!
Regarding your skills gaps, you may find these courses helpful on Coursera (I took them myself):
Data Science Math Skills - to review the basics and fill in any foundational gaps
Executive Data Science - for high level overview of the field and better understanding of types of roles available
You might also check out courses in these specializations (although I have not personally reviewed them):
Advanced Statistics for DS
Mathematics for Machine Learning
Algebra - Elementary to Advanced
Precalculus thru Data & Modeling
Differential Calculus thru Data & Modeling
Data Structures and Algorithms
*Note: specializations are not available to audit on Coursera, but you may audit each course within a specialization at no cost to you. Certificates available for a fee.
