Hi @muralimude, there are 3 types of competition in Google AdWords Keyword Planner bro, they are low, medium, and high. Personally, I don't really see this whenever I do my Keyword Research, this tool is for advertisers majorly and not for others. I just check the 'Avg. monthly searches' column and prepare my strategy according to that.
If you still stuck with this, you can check out @vinaykrkatiyar's post here:
