Depends on the persons motives and curiosity.. .

Just letting you know since I get the vibes that you're fairly new to this whole thing. You are not able to learn just hacking.
You need to learn programming and from there learn how to expl0it fuckas.

Hacking isn't something you can simply 'learn'. It's not one thing you can go and study. It's a mindset, a lifestyle. It will take years and years of honing various skills to become a decent 'hacker'.

It's always worth it to learn hacking, because hacking isn't specific to a certain field or technology. Back in the dark ages, 'hacking' was a big thing. Back when people were living in caves, 'hacking' was a big thing. Hacking is exploiting systems.

If you can't think outside the box, don't bother.
