Welcome to the community.
It is very difficult to find clicks are from bots or real people.
But Google has a very sophisticated monitoring system to protect advertisers from invalid clicks generated by bots.
Find more information in the link below
You can use the invalid clicks troubleshooter to get more information about specific questions
Hope this helps
The only way to tell if a click was a bot or a human is to look through your own web logs. Well behaved bots will identify themselves in the user agent data. They normally provide a link in the user agent data to further describe the function of the bot. There are a few "rogue" bots that do not identify themselves. Those are hard to identify directly, but you can identify them through a look at their behavior pattern. If you have on IP address that is making an unusually large number of page requests, or page requests with in an extremely short period of time (multiple requests within 2 or 3 second or less), that is likely a bot.
Best of Luck!

* Robots shown here gave hits or traffic "not viewed" by visitors, so they are not included in other charts. Numbers after + are successful hits on "robots.txt" files.
Do you know how Hits relates to Clicks and how can I tell if the bots visiting my site came there through Google Adwords?
Hits in your log are the same as click in AdWords. If the "hit" was from AdWords, the request query string data will include a gclid value (if you have auto-tagging enabled).
Best of Luck!
