Histogram Skew on Clustered Index
Your statistics are fine. 

It is telling you that you have 


exactly one row with value 1 
1 row with value 213152
1 row with value 213151
213,144 distinct values that are > 1 and &lt; 213,151 (so basically one row for each of the 213,149 possible integer values between that with 5 missing)
