Hello, hopefully I can help! I use 'hopefully' to mean 'I am not sure this is exactly what can happen, but I hope or wish that it will be what happens.'
Some examples: "I will learn French this year." I would say that if I were 100% sure that I am able to do that. But it's a hard goal, so maybe I will fail, so instead I might say, "Hopefully, I will learn this year."
I hope that makes sense. Good luck in with your learning goals. :)
