That might be what the clock says, but in reality, the exact winning time could be 9.571. Or it could be 9.572359. I think you see what I'm saying. The exact precise time could be any value in an interval. This right over here is a continuous random variable. Now, what would be the case, instead of saying the exact winning time, if instead I defined x to be the winning time of the men's 100-meter dash at the 2016 Olympics, rounded to the nearest hundredth? Is this a discrete or a continuous random variable?
