now i need to first learn what actually is vector art and typical settings etc , i see all tutorials using programs like illustrator or gimp is photoshop not good for vector art?
Haha, gimp and photoshop are not vector programs, they are raster/pixel programs. Illustrator and Inkscape are vector programs. Inkscape is free, go download it. Once you try to use it you will see how different it is from something like photoshop (assuming you've used photoshop). Vector art has a different mindset than raster/pixel art because in vector art you are placing points and dragging anchors to define automated curves and fills. There are no pixels.
