Not sure what LuckyOrange is, but you're making a few mistakes right away:

1. You never make a conclusion of an ad campaign based on the relation between impressions and clicks. You always take into account your final conversion.
2. To take the final conversion into account properly, you have to make sure you're tracking it properly, using the best tracking practices.
3. It's best to use the same analytics solution to track users from the very beginning to the very end of their journey. Classicalyy, the journey is from landing to the conversion.
4. There will always be difference between the data in different analytics systems because they track differently and have different definitions of things.
5. The difference between clicks and pageviews will always be different, but it's best to keep the difference as low as possible. A lot of things contribute to the difference: starting from donor sites putting ads in places where users are likely to misclick and finishing with the recipient site having rendering/tracking/timing problems.
6. In GA, you want to look at pageviews where the page is your ads landing page and users source and medium indicate your campaign. You compare that to your ad clicks.
