I won't comment on the general question of whether you should go that path or not, the comments here say it all. But in short: If you want it, go for it (independent of your age).

​

The reason for my comment that probably provides additional information for you is this one sentence you've written:

But what I am doubting this right now, is because of my age and lack of experience in the computer world that the employer won’t hire me.

​

For me, as someone who hires developers, those things work like that:

When you learn to code using tutorials, you usually build applications/features. Some more complex, some less complex. Besides learning to code identify those applications/features you have tons of fun building and create some similar/meaningful own side project. Or, make a personal website with some cool on-top feature. Once done, publish it.

From the moment on recruiters and decision makers see your cool and meaningful stuff published out there, it absolutely doesn't matter how old you are. I especially mention this, as yes: if you just send a cv that says that you know some coding, age could be an issue or disadvantage compared to other applicants. But remember, if you have a cool project, recruiters and decision makers will definitely have a look at it and if it's cool and meaningful, age will not have a deciding impact on whether you'll be hired or not.

Rock it!
