ADHD is a developmental condition which is highly genetic and relates to neurotransmitter brain chemistry (Dopamine / Norepinephrine). People with ADHD have it their whole life, it's not something you can develop in adulthood. However, people can be (commonly are) diagnosed in adulthood, especially for the inattentive subtype which has less outward symptoms.
What can change or develop over time is the life circumstances that a person with ADHD finds themselves in. Circumstance can make the difference between ADHD being a disorder with significant impairments vs a joyful and creative existence.
Situations which demand executive function, like putting down that mobile phone or closing youtube in favor of doing something more productive are much harder for people with ADHD. The market built by the tech industry to transact human attention for profit certainly hasn't helped here.
