ELI5: Why does Google give me twice as much storage space for my e-mails as it does for google drive? I don't need 10GB of space for e-mails but I sure could use it for cloud storage.

It's hard to look into the heads of googles' bosses, but probably because they assume that not many people actually fill up 10 GB of e-mails, but a lot of people will fill up 10 GB of cloud storage.

This means that the total amount of data google has to store is much lower this way.
