No. Paying for Google Maps Ads does not directly improve your organic Google Maps ranking. Google keeps paid advertising separate from organic rankings, so spending more on Maps Ads does not give your Business Profile a higher position in unpaid Maps results. (Google Help)
Maps Ads can still increase your overall visibility and customer interactions, but those are paid placements. Your organic Maps visibility is evaluated separately. So, if your goal is to improve organic ranking, focus on your Google Business Profile, relevance to local searches, and other factors that affect organic local visibility rather than increasing your ad budget.
