Is there a difference between Variant and Tuple type?

While reading some of the api documentation for DataStoreService | Roblox Creator Documentation and it’s members, particularly GlobalDataStore | Roblox Creator Documentation, I noticed that several functions said they returned the type of Variant while others said they returned the type of Tuple. However, when clicked, both links take you to the page for the type Tuple.

My question is this:
Is there a difference between the Variant or Tuple type? If there is a difference, is it an internal engine difference that won’t matter to me as I code? Should I treat them as the same?

Variant could be considered any and tuple is, not exactly, an unpacked table, also known as ...

Variant/any: all kinds of values (Vector3, CFrame, number, string)
Tuple: multiple values taken as one if using ...
