No. You do not have to grow up with a tool to learn a useful way to work with it. Experience can be a real advantage because you already know what customers need, where processes fail, and when an answer does not make sense.
Start with one familiar task rather than a broad course that feels overwhelming. Try improving a routine message, organizing a checklist, or exploring a topic you already know. Compare the result with your own standards. Progress means becoming more capable at something that matters to you, not keeping up with every new product.
