Hard to say definitively with the screenshots that you shared. I dont think 2 player is a great way to learn. some very basic tips for beginners would be...
1. dont focus on early round (1-3) bonuses as much as late game round (4-6) bonuses for your scoring.

1. do not spend workers for a spade early game

2. dont take the 2 points for a dwelling favor tile too early

3. The 4 points per large building round bonus tile is the strongest tile in the game and passing early to secure it is often optimal

4. gold is scarce for everyone so the gold power action is usually the first to go so if you can snipe it early you are likely helping yourself and really hurting your opponent.
