Hello,

If you do a internship after completing your graduation then it's okay. But sorry to say you didn't clear your query. That means where it's called year gap you didn't mention it, like if you go for higher studies after that or go for any permanent job.

Because if you go for higher studies then may be they will ask you why you didn't take admission in current year. Then you can show them your internship. If it's related in your subject then they will become happy. And it's not an issue.

If you go for any job, then this internship is not a year gap for you. Infact it's a good opportunity. You have experience for an internship before getting a job. So they will be happy about that.

All the best.
