Do you lose access to licensed images if I completely delete my adobe account?

I assume you mean what happens to licensed assets if you cancel your Adobe Stock Subscription. Per the T&C's:

14. Effect of Termination.
(A) If your subscription ends, or upon termination of these Additional Terms, then:
(1) you will forfeit all rights, title and interest in and to any and all unused credits or unused standard assets from a subscription plan, as applicable;
(2) except as set forth in section 9.4(D) (Effect of Termination of CC Pro Edition Plan), any perpetual licenses granted as to Stock Assets will survive and you may continue to use those licensed Stock Assets;
(3) you should download any Stock Assets that you have licensed, as such licensed Stock Assets may not be available after termination or expiration; and
(4) you should make note of any license validation codes issued upon license of an Audio Work, as such license codes may not be available after termination or expiration.
(B) If we terminate your right to use any Stock Asset(s) due to your breach of the Terms, you must cease all use, reproduction, modification, display, performance, distribution, and possession of any such Stock Asset(s).
