There are no certainties in law.
Your uncle appears to know he has done the wrong thing and wants to frighten you off. Based on your information you have a very good chance.
Without hearing from your uncle I can't evaluate how strong his case is going to be. My guess is that he'll say your grandmother verbally approved all the expenditure/gifts.
Having your grandmother declared as having legal capacity will help, especially if she contradicts the uncle's assertions.
