Any place that says VTY and VLAN are the same thing is junk.

A VTY line is used for SSH and Telnet access to the device. Here you configure login parameters and password.

A VLAN interface is in simplest terms the Layer 3 interface for a VLAN, allowing you to configure an IP address on it.

 

 

Edit:

An example of a VTY configuration:

line vty 0 4
 access-class SSH in
 exec-timeout 0 0
 privilege level 15
 password cisco.123
 logging synchronous
 transport preferred ssh
 transport input telnet ssh
 transport output all

 

An example of a VLAN Interface configuration:

interface Vlan15
 description Printers VLAN
 ip address 192.168.15.1 255.255.255.224
 ip helper-address 192.168.15.75
 ipv6 address 2606:A000:4390:7015::1/64
 ipv6 enable
 ipv6 dhcp relay destination 2606:A000:4390:7070::100
 ipv6 ospf 1 area 0

ok so it's the vty when configured helps me work with telnet and ssg and give me access while the vlan interface is where i will configure the ip address right and why there are so many vty's and we have only one default vlan that is vlan 1
