if you drive for a job, is it hard to not crash for i dunno, at least 5 years?

Depends on driver experience and the routes. If you're constantly going to unfamiliar places chances are it'll probably happen at some point. Driver skill and experience will mitigate this greatly. My dad travels up and down the country as part of his job, covering 100k+ miles in 2 years. The car is a long estate, so not the easiest to park but the car has zero kerbing on the wheels, and perhaps one or two very minor scrapes that may or may not have even been his fault. He's been doing this for over 5 years now without issues to his car but some of his colleagues have crashed their brand new company cars within a week of getting it (that guy was genuinely an unskilled driver).

Personally, I have the mentality of not even marking a single wheel let alone letting anything else major happen. Eventually you learn to anticipate, avoid tricky situations altogether and generally just lower the risk in everything you do. If you struggle with parking, then take some time to brush up on your skills and spacial awareness. If you're crashing at speed, then work on your anticipatory driving.
