Er, downloading can be anything and need not necessarily be illegal. Converting videos for phones is definitely not illegal, and ahem apps, well, I doubt anyone really cares. Most people here own Nokias, where you can get everything online anyway.
Can you guys tell me how to become a part time gamer???
Or game tester ie…
what is a part time ‘gammer’? .. a casual gammer ?? or a semi professional gammer? 
Start with the baby steps:
“Gamer”
Note the spelling please.
Next find a local architect who might want someone to render cad etc drawings for him.
He will pay you decently.
a local architect would give it to 3d guy to render his drawings , not to a guy who has a high end pc
Why not finish school first, properly, without skipping any topics, with good grades and focus on higher education and eventually a good career? 
Coming to your query, since i have posted something here, it’s also my duty to not leave it unanswered.
Invest some more money and join a course for animation/3dsmax or something like that.
Better still, don’t spend a single paisa and borrow/dwnld tutorials for 3dsmax etc.
In your free time now, when not gaming/playing, learn that well.
Depending on how bright and keen and dedicated you are, in a few months you should be skilled enough to freelance/work as a 3D visualiser/animator/2D artist/3D artist/character modeller/game developer/… on at least smaller projects or side jobs.
In your free time then, when not gaming/playing, work for 3D Arch firms, Gaming/game development companies or related projects and not only make some decent amount of money for yourself but also also a nice career out of the same maybe.
