Is "glad you ~" a spoken English? Is "I'm" skipped before it?

Yes, that's correct! The speaker has omitted the word "I'm" here, which is common when speaking. This expression is similar to "I'm so happy [x]," which also commonly has the word "I'm" omitted in the beginning. Ex: So glad it's not raining today. Ex: So happy class was canceled.
