The blurb on eventbrite states that all free and paid for talks are included in the gold pass. There are some exceptions like diamond talks although this year even some of those are included. On top of that there are two other diamond talks vouchers included in the gold pass. So my reading of this is that all talks (excluding those diamond talks where it states they are specifically excluded) are included unless it states they are not. I think that makes sense! Happy to be corrected though!
