Is that your current total SC count? Item collections usually eat up a ton of SCs. Average SC amount spendage would be somewhere in the mid-20s to 30s while max would be below 40-50 (if you have extremely bad luck). If you spend no SCs at all, the most you'll get is around half of the total amount of items you need to get for a perfect unit. The maximum amount of items are usually between 700-1600 depending on the map drops.
The first red tab is skill awakening where you need the same orbs you used to AW your desired unit and S.AW fairy dropped from the AW unit-only map on weekend dailies. The second tab is for special awakening for units that require 2 different orbs to AW. For example, princesses require unicorn knight orbs and rune fencer orbs to awaken.
