Struggling to achieve 1800 rating.

I don't understand. Your highest rating here is your blitz rating- 1442.

It is very unlikely that anyone here is going to be able to tell you how you specifically and individually are falling short. And any general advice about the difference between 1700 and 1800 players is going to be, definitionally, only possibly applicable to your situation and not a definitive diagnosis.
Got get a coach, and have them work with you to analyze your strengths and weaknesses and get your question answered properly.

What made the difference for me was studying pawn structures by Andrew Soltis book and studying tactics. Both subjects are HUGE on the level of importance in improving.

Getting stuck at a rating for a while is normal even if you've been trying to improve. Although if you haven't been able to move your rating after a year you should consider trying new training methods. Usually focusing on a weak area or doing that thing you "don't like." Maybe that's endgames, or playing sharp openings, or playing faster or slower, or something else.
There are lots of ways to gain 100 points especially when you're not a GM, so every individual is different. The general areas are openings, endgames, strategy, tactics, and annotated game collections. I recommend getting a classic or otherwise widely recommended book on one of those, and then spending a few hour a day (every day) going over it. Usually your weakest area is something you've avoided studying because it's "boring" or "difficult" or something like this. Once you're stuck, improving usually means stepping outside of your comfort zone.
Played in tournaments, reviewed games with an engine, reviewed my openings against a reference (chessbase), read books. With books I would usually read it twice. First time somewhat quickly, and taking some notes, 2nd time to review areas I found difficult and/or interesting. I've only read a few books like this, but each time I noticeably improved. Read every page and play over all the analysis.
I also solved a lot of tactics, out of a book, visualizing the entire solution to the end before checking if my answer was correct. (I tend to look down on online tactics which let you see the pieces move as you're doing the tactic).
Based upon your response in #5, I'm guessing you are around 12- to 13-years-old now? 1700 at that age is a fairly strong rating.
As to how to break your current plateau, you will need someone to look at your games. Looking at your last one, for example, you forced trades when you had static weaknesses (your pawn structure was shot), which simply allows (in fact, encourages) your opponent to simplify into a winning endgame. Find a stronger player at a local club to go over some games you have already self-annotated and point out where you could have done better.
