 Dofollow links allow google to follow them and reach our website. Giving us link juice and a backlink. If a webmaster is linking back to you with this link both Search Engine and Humans will be able to follow you and No Follow doesn't pass link juice.

Do follow links are the links which can be created by the dofollow sites or backlinks.
Nofollow links are the links which can be created by the nofollow sites which can be not useful for getting the traffic for the website.

Dofollow links -> Google bot will follow this links then add this link in to database of it
Nofollow links -> Google doesn't folow this links and your backlink won't count

Do follow and no follow are link attributes and contain instructions for search engine robots. Do follow links are crawled and indexed in search engines whereas no follow links are never crawled and indexed in search engines.

Nofollow is an HTML attribute value used to instruct search engines bots that a hyperlink should not influence the link target’s ranking in the search engine’s index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamdexing from occurring in the first place.

Nofollow links attributes do not allow search engine bots to follow link. That means if the website owner is linking back to you with nofollow attributes, it does not pass on link juice. Only Humans will be able to follow the links.

Dofollow link-  are links  that count as points, pushing SEO link juice and boosting the page rank of the linked-to sites, helping them go higher in the SERPs as a result.
Nofollow link us a link that does not count as a point in the page's favor, does not boost PageRank, and doesn't help a page's placement  in the SERP's.
