There are (almost) no stupid questions - yours certainly isn't!
I see that you unanimously played CTTH and some Blitz - I can't especially cope with that.
Generally speaking, there are a few factors influencing the shots significantly and beyond belief.
1) is that they vary with different probabilities, giving you a WTF shot in the extreme.
2) is that shot quality depends on the equipment used.
You have Starter and low level equipment in your bag, and this is prone to imprecise shooting. Don't worry, you can advance with it, but it may become difficult in some future. So, choose wisely if you want to become better and "suffer" more difficult environment due to tiering up, and subsequently, investments.
Mind you, playing ranked strokeplay is an almost inevitable prerequisite to advancing ;)
