You don't have to consciously and rationally understand the grammar - you didn't when first learning to speak your first language!
Stephen Krashen is a pretty good researcher on this - the summary is that exposure to the language for time (e.g. 500 hours of content you just about understand) is the critical factor. This is training non-conscious parts of your brain's neural network.
Some people like understanding the grammar and structure of a language consciously, and it can help as a mnemonic aid for anyone. But it isn't necessary, or the critical process.

Also, if you're looking for entertaining reading in your target language, grammar books are going to be interesting to you. The goal during language learning is to find interesting content that you understand, and your target language's grammar is a known hobby of yours.
A very interesting point, I stand corrected. When I think about it, my brain usually does strongly prefer to consciously create a set of "rules" about a knowledge base rather than unconsciously memorize a set of ready-made samples. But that might be just me.
I feel like it's the opposite. Most people who speak languages with complex grammar natively can not clearly explain the grammar to you, because they use the correct grammar intuitively, and they have learned to do so by having a ton of input in that language.
This is a bad example because it's probably more wordy/complex than it needs to be but I couldn't begin to name the various grammar being used in: "I would not have gone to Paris except that a friend decided to give me a free ticket."
Good luck getting a 3 year old Finnish person lecturing you on Finnish grammar - Even though the kid can easily ask for a ice cream in both past, present, and future.
