They simply haven't banned your account. You've been suspended, happens to many people. If you appeal to them and start following their TOS, you'll be fine.
Suspended = banned in adwords. You can try appealing if you want to waste your time talking to a chat bot and them rejecting your appeal a few days later.
I don't think they make the distinction between "suspended" and "banned". As they seem to only use the former... As suspended (which can also mean permanently suspended).
When you do contact them, and you use gmail, make sure to check your junk/spam folder for their reply (mine was there).
