console 0 is the physical console port on the switch/router you plug into.

line vty is when you remote into the switch/router via telnet or ssh.

the config-line is letting you know you are currently in configuration mode for that specific line.

Some commands are also different in relation to them. Mostly regarding Access lists and security.
But CDX nailed the biggest differences.

i heard that vty is the virtual port and ttf is the physical port, so is console 0 practically ttf?

I think you mean to say "TTY" port. Yes, these TTYs are physical ports. Common on a terminal server that has array ASYNC cards the consoles lines into multiple devices to their con 0 port for console management purposes.

answer = yes, line console 0 is one type of TTY port.

tty = physical
vty = virtual

line console 0 = physical

All lines are TTY (Teletype) meaning you type on a keyboard and the characters written out somewhere. Pretty much all CLI windows are a form of TTY.

Then you have different types of TTY. virtual (VTY), console (CTY or CON), auxiliary (AUX), TTY (Generic). The different types of lines may all show up as (config-line) but depending on the type of line you will have different configurations available like sending out modem strings, configuring signal levels, configuring reverse telnet, etc...
