It's not about how long a chapter is, but what the chapter is. Some stories occasionally have chapters upwards of 10k words long, but if they are engaging, people will still like them. The basic rule of thumb is that the longer the chapter is, the better your writing needs to be or you'll make it tedious and unenjoyable to read.
But I got a little derailed, so to answer your question, 3k words for the first chapter is quite a lot. Most stories hover around 2k. But 3k is absolutely fine, as long as it's not an exception; it definitely shouldn't be the longest chapter in the story.
