You should only occasionally ever have to solve pictures unless youve been blacklisted, 90% of the time it should just be a checkbox. To know for sure if youve been blacklisted you can click the audio icon, if it gives an error then your Google account was put on a bot list and you need to create a new one or use incognito mode. Also if you are selecting things like cars and storefronts and the new tiles load slowly rather than instantly then youve been blacklisted. On a clean account the captchas are very easy.
