Does Celery for this task?

Good day!
There is a python script that takes the data from the dB and puts them in redis.
This script includes 2 methods:
1) update all data
2) update the latest data
These two methods I want to execute periodically, the 1st time a day, 2nd time in five seconds.
Plan to use Celery, actually a question, task, Celery will execute tasks sequentially? Ie let's say I will use both methods in the same queue, and when for example starts execution of the 1st method, then the execution of the 2nd will not start until a completes the execution of the 1st? Did I understand correctly?
And another question what is best practice for such tasks?
