How to read this

Possible labels: Every simple string of that length before the dot, using a–z and 0–9 (36 options per character).
Tracked checks: How many checks have run for labels of that length across the top-100 TLD collection scope. A label may be checked on one TLD, several, or none — so this is checks performed, not a complete labels × TLDs grid.
Unregistered: Resolved to no DNS at check time. Unused / parked means registered but showing no active service.

Aggregates only — no individual domain is listed or stored. For the major TLDs tracked here, essentially every 1–3 character label is already taken. WHOIS and registration records are operated by each registry or registrar; dom4in.net does not query WHOIS directly.
