Translation:The people are similar.
닮다 means to resemble and usually used for two people that look alike, such as 딸이 너를 진짜 닮았어! (Your daughter really looks like you [notice 닮다 is usually past tense]). 비슷하다 can be used when anything is similar, like "film" and "movie" or "feeling glad" and "feeling content."
When pronouncing 비슷해요, is the consonant ㅅ pronounced with a hard "cht" sound?
My understanding of ㅅ at the end of a syllable, especially with a consonant following, sounds like soft/lazy t in English; where the sound just sort of stops without your tongue touching your teeth.
