I prefer Photoshop, the good thing about it is there are millions of free online tutorials, brushes and effects.
If you want a free version that is comparable there is GIMP. Linux based but can perform most of the same effects.
When you get into logo design you are going to find physical print shops (not sure if this applies) when doing banners or brochures are going to want a vector based graphic in which case Illustrator is what you want. It might be because I knew about Photoshop first but I had a steeper learning curve with Illustrator then with Photoshop.
If you have questions keep asking.
At no age should someone 'know' these things. It would seem that you simply haven't had to know. There is always time to learn.
Ask a question you are a fool for a moment.
Never ask a question you are a fool for life.
