A like is generally a symbol of someone enjoying your content, but it's also king to observe what happens as a like train comes in. As OnlyUltimate said, the share depend on who shares them and whether or not anyone linked to that person is going to interact with the post, but also looking at the way that likes come in, my most liked video has 95 likes and almost 17000 views, meaning 2000 likes would generate almost 360000 views. This because likes are the result of viewership and aren't just something that happens.
