Solving tactics are good for the thought process (calculating forcing moves) and the themes (like forks, removing the defender, discovered attack, etc). These two elements (calculation and tactical themes) can be applied to all sorts of positions.
If you want to do tactics (and this is the best way to avoid blunders as a new player) then I don't recommend doing tactics online. I recommend a book like this because it breaks them into themes and gives some explanations:

If that's unappealing to you for whatever reason, the other basic areas are openings, strategy, and endgames. New players can improve no matter what they study, but absolutely foundational is not giving away pieces for free to 0, 1, and 2 move combinations (by zero move I mean you just leave an attacked piece undefended). Solving tactics helps you practice calculating these sorts of moves and form good habits (all while also improving your tactics).
For practice long live games are better than speed games.
Hi I am very new to chess. I am trying to learn as much as I can, but don't seem to be learning very much just playing blitz. I made a lot of progress at first but I felt as if it was mostly just lucky games.
At the moment my games are either vs people who make no mistakes or blunders in the first 20 moves, or people who blunder their queen on move 5. I don't really know how I am supposed to learn from this at all. I try not to give up games where I blunder to an easy tactic like pinning my queen to my king on accident or hanging a rook in the opening to a early queen move, but it doesn't really seem to sink in.
I've tried tactic training, but I never really see those tactics in my games. I almost feel as if I only win if my opponent plays very poorly and blunders something I can take in one move. If they don't blunder like that, I do eventually and just lose.
How can I start seeing all of my blunders so I can start to get better?
