The times I've grown the most are when I've jumped in the deep end. People aren't hiring you for your coding, despite what they might tell you. They're really hiring you for your problem solving ability. So don't worry about it. The times I've learned the most are when somehow I've ended up in a job where I know nothing. I might not know the language (this is how I ended up learning things like C# and python, java, etc) but just keep searching and reasoning your way through it. If you're new to something, you'll be learning lots of things left and right because it's all new to you. Same for jobs (different companies do things differently), people, projects, etc. Getting around and trying more is really all you can do to get that real world experience. Just don't be afraid when people say no. Or find a place where your deep knowledge can help them, and then you can also pick up some of the other things they do. It also sounds like you don't interact with a lot of other teams or codebases that may exist (or may not) at your job. Maybe offer to try some of their easy tickets to just get acquainted with it? (your boss might even love that you care)
