Usage statistics come from sys.dm_db_index_usage_stats, which tracks the number of execution plans that include an operator touching that index. It's reset on SQL Server service restart, or when the index is modified.
Operational statistics come from sys.dm_db_index_operational_stats, which track the number of times the index has actually been touched. It's reset on a different schedule - when that object's metadata disappears from cache.
