Earth,
First off, drop the hyperbole. I understand the frustration, but nobody can help you if you aren't actually realistic about your problems and struggles with the game. If you are literally 4-putting from 3 feet out, then the problem is your skill and not the game.
As many have said, WGT has an element of realism built in. This means that you could ding a shot, and aim exactly where you want, and the result might not be what you thought. Chances are itll be close, but there is that bit of randomness / realism. Especially with the starter clubs, which have horrible precision (basically meaning that even if you ding, the area where your ball could end up is large).
And I will second the point made about you not knowing what ranked rounds are. Ranked rounds are simply rounds that you play that count towards your stats. It also helps a lot to play with others, because then you can ask them questions during play (provided you get matched up with decent folk). Or you could invite one of the many experts that have posted on here, or throughout the forums. I am sure they will be more than helpful.
This game comes down to knowing your club yardage, being able to hit the ding, and putting. Green speeds are faster the higher up you go, so a 25 ft putt, level, will not always be 100% of a 25 ft meter putter. Add onto that uphill, downhill, and reading break just like actual golf. Keep practicing, getting familiar, and I highly recommend watching videos and doing surveys for credits so you can upgrade your gear. Best of luck, this game is pretty fun once you get past the frustration.
