It's up to you to continue the tutorial or not but the game is even easyer since you get a lot AI help. You may want to come back to the tutorial after your first demo game.
Don't know what to research? just pick one the AI recommend (top of the list)
Don't know what to build? again look at the two options AI recommends.
Also you can let the gov in a cities decide what to build.
Don't know what your workers should build or where to put roads? you can put your workers on auto.
When you pick a settler it will even give hints where to build a city by circling squares on the map. (These blue circles is usually good place to build cities but not always the best. This is something you'll learn with time)
Every game you will learn more how to play and your strategy will get deeper and rely less on the AI.
So you don't have to learn everything in one game.
