In the last ten years we have one (1) accidental satellite collision. In 2021 when a Chinese spy satellite in a 788km orbit collided with an old rocket stage from the 90s. There was also that Indian anti-satellite weapon hitting a microsat in 2019, but that was very much intentional (and much condemned because of all the fragments it caused)

In the decade before that (so 2006-2015) we had four accidental collisions and two anti-satellite tests (China and US)

Those are not frequent events. And if you attribute any statistical significance to them, it seems we are getting much better at avoiding collisions
