As a novice, start out cheap and simple. Shoot and shoot until you wear out the camera. One of the differences between an inexpensive camera and an expensive camera is Image Quality (IQ), the sharpness, noise (grain) and tonal range of the image. Modern digital cameras are so good that up to an 11x14 you won't be able to tell the difference between an inexpensive camera and the flagship model (under normal/daylight lighting conditions). So get an entry level camera with a kit lens and shoot the hell out of it ... until the wheels fall off ... Don't upgrade until you feel the camera is holding you back ... significantly holding you back. At that point you should know what you need and want in order to advance and with only an entry level camera as your investment, you're not really locked into any particular system or manufacturer.
Photography is a lot of things, one of which is 'craft'. Like most crafts the more you do the better your skills. Don't ever think that good equipment can compensate for lack of experience and skill. (i.e. Just because you have a pro set of golf clubs doesn't make you a pro golfer.). Look at a long commitment before attaining a pro level of shooting. Remember that one of the big differences between a pro and non-pro is consistency. Capturing the exception image every now and then doesn't make you a pro ... A pro needs to be able to consistency capture the exceptional image day-in and day-out ... on demand.
Good Luck and Good Shooting,
Gary
