General Question on Access-lists if not applied to vlan interface

Hi All

Just a quick question for a confirmation.
If i have a bunch of vlans and only some have `ip access-group <description> in` and others do not.
But i have a bunch of ip access-groups unassigned to Vlan interfaces.
Will the vlans with unassigned ip access-groups read/apply all the ip access-groups that are unassigned?

e.g.
interface vlan10
ip access-group vlan10 in

interface vlan20
Interface vlan30

ip access-list vlan10
ip access-list wifi
ip access-list storage

So vlan 20 and 30 will both get the acls for access-group wifi and storage?

Thanks

No other vlan will not use acl and traffic will permit.

But notice that the direction of acl apply to vlan is important
