No. The number of Overrank skill is based on the level of the special job class, not the total level of the player. For example Ainz has 5 levels in Overlord which means he has 5 overrank skills.

The number of times you can an overrank skill is dependent on the total level of the player.

Level 70 - can cast once a day

Level 80 - can cast twice a day

Level 90 - can cast thrice a day

Level 100 - can cast 4 times  a day

It is currently unknown whether the limitation applies to "a single spell" or "to each and every spell"
