3D printing is a big complex subject so there is a lot to learn. Yes you can probably print something simple fairly easily but there are many adjustable variables that can effect the print quality. Its not so much the printer itself as how you drive it.
Printing requires two features if you want to create an object yourself.
A computer aided design programme to create an object in electronic form. This than has to be converted into a file that a slicer programme can convert into a sequential but long set of instructions that the printer can follow.
The printer itself has many settings (hundreds!) some of which you may have to 'adjust' to get the best print quality.
You can obtain a 'slicer ready' file (an stl file) but note there are several slightly different slicer programmes and the settings for a good print can depend on the model of printer or even the type of filament that you are using.
There is a lot to be said for buying one of the most popular printers. It may not have the ultimate 'bells and whistles' but its very popularity will ensure there is plenty of on line advice available to help solve specific problems
