How long does it take to learn UI UX?

I'm curious, how long does it typically take for someone to learn UI UX design? Is it a matter of weeks, months, or even years? And what factors might influence the duration of the learning process? Is it more about the individual's prior experience, the intensity of their studies, or perhaps the quality of the educational resources they have access to? I'm eager to understand the time frame and what goes into mastering this field.
