Don't underestimate the fundamentals, this is a great resource.
First, your gun is likely of excellent quality and I wouldn't jump to the idea the sights are off.
Anticipation is a reflex we have to fight every time we train. Please check out the article. Anticipation or "flinching" is usually tied to jerking the trigger which pulls the gun to the left if you are right handed. Try shooting with the other hand. Do you now shoot low right? Also try letting a very experienced shooter try a few shots and it'll help give an idea of what the gun is doing.
Front sight focus: this is very important and when I started shooting I didn't start to understand this until at least the fifth range trip. After you find your sight picture, Focus on the front sight with your eyes and don't look at the target or the rear sights. Both should be fuzzy in comparison to the front sight. Focus on that sight so well that if there were tiny words you could read them off it. Keep focusing on it as you take out the slack in the trigger and slowly press it straight back to the rear. And be honest with yourself - did you maintain focus on that sight even as the trigger went past the point of no return? Watch it Until the end and even afterwards : track the front sight until it settles down again after the shot all the while resisting the urge to focus your eyes on the target to check how you did. That's the follow through.
This is just the tip of the iceberg. It's a lot of fun when you see yourself getting better and your groups will magically shrink although you are doing things your body doesn't find natural to such as slowly pressing the trigger to the rear until it fires by itself rather than "now!" And focusing on the front sight.
About the trigger break: it's not like clicking a mouse where you do it all at once. Think of it like a heavy cardboard box on carpet. You give it some force, it doesn't move at first. Then a little more, a little more until it starts sliding. When we press the trigger, slowly increase how much force you use until you use just enough to get the trigger moving to the rear and no more. Once the trigger is moving your only other job is to focus on that front sight, hold it steady with even moderate pressure in your grip. You'd be surprised how other muscles in your hand want to clench when you know an explosion will occur but resist. In fact id practice gripping your wrist or gun with your hand and keeping even pressure while moving only the trigger finger. You'll find you have to deliberately stop other muscles from twitching. That's isolating the trigger finger. Good luck.
