What you're seeing is normal - Linux does not use "drive letters" (C:\, D:\ etc.) like Windows. The file-manager happens to be showing user Pi's "home" and "desktop" directories by default. If you go up two levels (to /home and then /) you will see the rest of the SDHC card's file structure. Note also, that if you used NOOBS to install the O.S. (Raspbian, I guess) that NOOBS' recovery partition will take up around 1.2Gb (and this, "FAT" partition, will be the only one visible to Windows which doesn't understand Linux partition types).

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Like Trevor said, drive letters do not exist under unix. If they did I have seen some systems that would be severely limited by the alphabet as they had hundreds of file systems (drives) mounted.
What happens under unix is that a file system is mounted someplace under root. For example if there were 3 groups that wanted to give their users their own drive, they might mount each drive as follows:

/home/tech
/home/engineers
/home/marketing

So the questions are what size are the drives, and where are they? df will show you what you want to know.

In short, each drive becomes a seamless and integral part of the directory tree.
