Yes, it is possible to improve your English fluency without learning grammar.
In fact, there are circumstances (though there are exceptions to this) where it’s actually quite advisable not to learn grammar.
And this is because English learners tend to focus too much on grammar. You tend to have this over-reliance on grammar rules. Teachers in your school probably taught you English like how you should solve mathematical equations. And if you get the answer wrong, you’re immediately screwed and your grades are going to tank. But this is an absolutely horrible way to teach (and learn) English.
The reality is, native English speakers don’t even speak the way students were taught in school. Instead, we native English speakers store large blocks of English which we call “chunks” in our long-term memory (I talk more about “chunks” in this video). Then, when it’s time to use these blocks of English, we just pull them out of memory and use them.
Now, of course, this isn’t to say that grammar rules aren’t completely useless. They’re not. You just need the proper time and place to learn and study them. But that’s when you’re already fluent in English, and you need to just polish it up a bit more by learning about grammar and whatnot.
So, again, yes, it is possible to improve your English without grammar. And instead of overthinking grammar, what you should do instead is to change the way you learn. Find out better ways to approach learning English. In fact, you can start learning more about the best methods to learn English with the free one-hour training that I created.

Hope that helps.
