My advice to you is first of all, don't take the advice of armchair manga artists in the comments too seriously. Very few people here have drawn manga, and no one you'll find here held a serialization in Japan, so there's a limit to how useful the opinions you'll get are. I'll still share my opinion or at least what I would've told me when I was your level, but take it with a grain of salt.
Asking clueless people whether you have talent is meaningless. In fact, asking about talent in the first place is meaningless. Believing in talent can only hinder your progress: either you think you're talented and you stop working hard enough, or you think you're talentless and you lose hope. There is no benefit to even believing that talent is a thing. the faster you let go of "talent", the faster you will improve. Think of talent as a magical trait that separates the best in the world from the second best. You don't need talent to just be a professional artist, that much you can get just by practicing long enough. This isn't just my opinion, most manga artists genuinely believe this, which is why characters like Rock Lee are so common. You'll be hard pressed to find an artist who thinks he got anywhere by having talent. They all know how hard they worked. Talent might make you the best inexperienced artist in a grade school playground, but it will not matter when it comes to drawing real professional stuff.
Next, don't let anyone tell you that you can't be a manga artist in Japan. It is hard, but the difference between hard and impossible is literally infinite. There's many Japanese publishers reaching out to the west, and contests such as Weekly Shonen Jump's Treasure Award are open internationally, to everyone.
Yes, you will have to learn Japanese, yes, you will have to move to Japan, yes, there are some inconveniences you'll face that Japanese born manga artists don't have to face. No, it is not impossible.
The real question is what you want to do with your life. If you can wholeheartedly say that you will give your life to manga, nothing can stop you. But if you're just casually looking at this as a hobby, well, then it doesn't really matter, but you won't get anywhere.
