31 years old - Career Change?

I’m a 31yr old (almost 32) truck Mechanic

Is it too late to begin working towards a career in cyber security? Ie starting to study foundational IT knowledge in my own time and then building on that with certifications?

If I dedicated a few hours per day after work to study over 12 to 24 months what level could I realistically expect to achieve?

My current IT knowledge is limited, but I at least grew up with computers so am competent using them but that’s about it.

I’m obviously looking for a career change and just want to know if this is a realistic possibility. I would rather get honest advice about expectations as opposed to the “it’s never too late” but I appreciate any replies. Thanks.
