A conversion from Chapter 7 to 13 is possible, although it's not an automatic thing. In a Chapter 7 case, a Chapter 7 trustee gets appointed to administer the assets in your bankruptcy estate.

What I see sometimes, prominently with people who are not represented by a qualified attorney when they file, is that they file Chapter 7 with assets that they would lose, and then they try to convert the case to a Chapter 13 to save those assets.

Well, the Chapter 7 trustee won't allow that to happen, so it's very important before you actually file the Chapter 7 to make sure that you've consulted with a qualified bankruptcy attorney so that you're not in that position.
