Yes, I never used any of those but it looks like they followed suit on the RH success and implemented something similar.
I had an Interactive Brokers account for years and there the distinction is very clear. A cash account just can't use money before they are settled (not different from many bank accounts show you two balance, one available the other one including pending transactions). To upgrade to a margin account you need to go through a rather long process of documents and signatures.
