This is true. The number of seedlings of plants that die off often depends on 2 factors:
1. The type of orchid it is.
Some orchids are very sensitive to changes or are physically delicate, so when they are deflasked, the odds in favor of them dying can be high.
2. The skill or experience of the grower at hardening off the seedlings.
Hardening off a seedling means that the cells of the plants are acclimated to growing outside of a protected flask environment.
Seedlings can die off in large amounts. A 100% die off is not unheard of. There's a reason why orchids produce lots of dust-like seeds - it's a numbers game.
Like with anything skill or experience related, the more often you do it, and the more rapidly and effectively you learn from your experiences to make any necessary adjustments in your techniques, fewer seedlings die.

Again, true. That's what the hardening off process is about - acclimating them to the outside world.
Different kinds of orchid seedlings will harden off much faster than others.
