Statistically, depending on the source it's somewhere around 15-20% of people who say that they met their spouse at university. Obviously that's the minority on any reading, but many of those people will have had other relationships at university before meeting their future spouse, given that most people are at university for at least three or four years.
In practice, though, everyone's experience is unique. Even if you don't get into a serious relationship at university or meet your future spouse, the experience of being in relationships that don't work out is valuable in and of itself, as are social interactions generally at university, whether intimate or not. It's really a matter of being open to new experiences whilst being aware of your own preferences and boundaries. Doing something that you ultimately don't like or even regret is not a bad thing. It'll happen a lot in your life, but those experiences are just as valuable ultimately as the ones that you enjoy, if not more so in many ways. There's no correct way to do any of this. It's for you to decide how to go about it ultimately.
