I am scared that I'll "grow out" of being trans

So before anyone comes at me, yes, I am well aware that something like a "trans phase" doesn't exist, but I've recently googled some stuff about this type of thing and found some studies that showed that they did a test on trans youth a while ago and found out that like there were a few people that didn't show any signs of gender dysphoria and "changed their mind" (whatever that means).

I don't have lots of dysphoria, almost none, what I feel I wouldn't describe as dysphoria and so that's a thing where I kinda feel separated from a lot of other trans people and their experience, I can't really relate to a lot of that stuff. I want to be a guy, and although I have my doubts like any other person, I am pretty sure of that but now I'm just kinda worried that when I'm older I will feel otherwise.

I've had these thoughts before but now they've just gotten more intense. I forgot to mention, I am a teen. Both of my parents kinda know but don't really believe that I'll stick to it because they think it's a "trend".

Thanks for any answers!
