Pivoting from bank teller to something new (update)

After 12 years as a bank teller I am thinking about moving into a different field. I have read a lot of threads here and could not find my exact situation. I have a little time and a small budget for training. Has anyone made a similar move?

I began with informational chats, then a short online course, then a related entry-level role. It took about 8 months.
