If there are any outside_access_out or inside_access_out or inside_access_in rules then it means there is some outbound filtering.
If they’re all outside_access_in then it means there is not.
What is the difference between inside_access_in and inside_access_out ?
Inside_access_in and Inside_access_out are just friendly names for your access lists.
Inside_access_in is an ‘Inbound’ access-list, and inside_access_out is an ‘Outbound’ access list. An inbound access-list is applied to traffic as it ENTERS that interface. Inversely, an outbound access-list is applied to traffic as it EXITS that interface. So if you apply an inbound access-list to your inside interface, then it will apply to traffic that enters the inside interface from the inside network.
