In reply to Fultonius:
In total agreement with this, but an additional bit of logic that might help the OP:
These are typical, not universal, observations...
In skiing (off piste) a high proportion of the sport is spent on or under slopes in the range of angles that avalanche. Skis allow a lot of ground to be covered, so the skier is exposed to a relatively large number of slopes, and wide route-planning and choosing options (you go a long way from the "known" conditions of your starting point and you get lots of choices how to come back.) Skis are also a natural cutting-tool for starting avalanches.
In climbing, more often you are walking directly the shortest way to the foot of a route. You're more likely to be post-holing up a slope - or the high side of a slope - that you've recce'd in advance than coming over a col and slicing a fracture line across a slope you've only just seen, and your slow progress (and intimacy with the snow...) will benefit your ability to keep a close eye on conditions underfoot. And you might only see the one slope in the day, if you come back down the same way.
Skiers are typically spending a lot more time at actually, or potentially*, higher risk - and in situations where an avalanche might be survivable.

*The trick being to have the skills to choose routes that allow you to get some nice miles done in conditions of actual safety without having to stop for an hour at every slope to hem and haw and dig numerous pits...
