Low Volume on Keyword Planner/Semrush, but Good Impressions on Search Console

Working on certain keyword for some geographies, Search Console shows impressions in the range of 300-500 in the span of 28 days (with average rank in the late 20s). For the exact query, it is 100+ impressions. However, Semrush and Keyword Planner Tool are showing a monthly search volume of 10 for the same regions. If there are not enough searches, then how can it get impressions?
