Two things in orbit may crash. One’s a spent Chinese rocket booster, the other is a Russian satellite no longer in service. Probability is > 10%. They don’t give anything more exact than that, but it almost certainly means less than 20%. So quite likely it won’t happen, although you won’t realize that from all the headlines about it. From the tweets,
miss distance: < 12 meters
relative speed: 14 km/sec
combined mass: 2800 kg
altitude: 991 km.
