Current Quoted Usage:

Intended Usage:

There are two questions here.
First, factor and variable are often used interchangeably, but they are not synonymous. From Merriam-Webster, factor can be defined as "one that actively contributes to the production of a result," and variable as "an element, feature, or factor that is liable to vary or change."
Factor necessarily implies a statement of causality/relationship between X and Y, which is not necessarily the case for variable.
Second, the phrases "x-factor" and "x-variable" are not interchangeable in the context you provide. X-factor is defined as "a circumstance, quality, or person that has a strong but unpredictable influence."
It is generally used in a positive sense. For instance, "He's a singer who has the X factor."
In your example, the team has the X factor, which is a selling point/positive attribute. I am not familiar with "x-variable" as a term at all, and certainly not as one interchangeable with "x-factor" in that sense.
