So a chiral centre is "a carbon that is attached to four different groups". But does this group include the whole chain, or just the adjacent carbon(s)?

For instance, for glucose, shown attached, would carbon 3 not be considered a chiral centre because it is bonded to two CHOH groups, or a chiral centre because the rest of the whole compound is different, C4-C6 as one group and C1-C2 as another?

Thanks.

You have to look at the whole chain. C3 as you have indicated is indeed a stereogenic centre
