Does it look bad if an applicant took a career break (1 year) for self-improvement?

Anonymous

I am considering a career change.

I want to learn skills (e. g. AI, Machine Learning, etc.) that would help me with that career change, but it is not easy for me to make time for it as I work more than 40 hrs a week. I would like to quit my job and focus on developing skills full time.

I have enough money saved to do this.

My goal is to create a portfolio of projects demonstrating my newly learned skills.

I am not getting any younger and I am not sure how easy it will be for me to learn things when I am older.
