"Not much in it" is an informal expression that people often use when there is very little difference between two things. For example, if you are comparing two cars and one has slightly better gas mileage but is more expensive, you might say "there's not much in it" to indicate that the difference is not significant. You can also use this expression in sports to describe a close match where both teams are evenly matched and neither one is clearly better. Overall, "not much in it" is a way to express that the difference between two things is small or insignificant.
