yes that is correct; find the underlying tables of those views, and update stats on them;

you could also use something like this to blindly update all stats for all tables as a shotgun approach:

DECLARE @Exec VARCHAR(MAX)

SELECT @Exec = ''

SELECT @Exec = 'UPDATE STATISTICS ' + QUOTENAME(schema_name(schema_id))+ '.' + quotename(name) + ' WITH FULLSCAN ; ' + CHAR(13) + CHAR(10) + @Exec

FROM sys.tables

ORDER BY name DESC

PRINT LEN(@Exec)

PRINT @Exec

EXEC(@Exec)
