The 192,000 is how much cash you make. You will lose on average 700-900 fans for one of those when challenged like you were. When you start a match you not only get the 192,000 cash but gain 1000 fans back unless you have the Max fans for your stadium already. You are limited to a certain amount of matches per day, so when they all disappear from the map don't worry as more teams will come to replace them
The best way of checking what you gained or lost it to click on match, then schedule, then click on the match itself there. On the first screen you see it has the amount not cash earned and the number of fans gained. It will always be 1000 unless you have more than 142000 fans or have space left for less than 1000 until you're at max capacity
