Translation:I don't like studying.
In everyday usage, no difference. However if you really want to dig into details... "dislike" means you have a negative feeling about something. "Don't like", if you take the two words apart, can mean that you do not feel positive about something, but it does not say that you feel negative (or not) about it. Think of it as "dislike" being < 0, and "don't like" being ≤ 0.
