Josh Saviano, who played Kevin’s best friend Paul, left acting after the show ended. Olivia d’Abo, who played the older sister Karen, has had a steady acting career, but she was already 19 when the show premiered.
One of the Sprouse twins from Zack and Cody went on to act in other shows.
Oh, Cole Sprouse was on Riverdale
Kelly from Married with Children went on to other acting roles on movies. (Applegate)
Candace Cameron Bure. Lets not forget her success.
Many young actors from Disney channel went on to being very successful. Ariana Grande.

Yes, but how many of them wound up being successful actors as adults, as the OP asks?
I think all of them acted afterward.
Barry and Maureen were the most sucessful.
Susan was a train wreck for awhile. She has some credits after cleaning up.
None were stars afterwards.
The TV series based on Paper Moon was not successful, but their Addie Pray was played by 12 year old Jodie Foster, who has been quite successful as an actress since then.
That 70’s show? I know for a fact Mila Kunis and Laura Prepon were under 18 when that started. Some of the others may have been just around 18 at that time.
Kunis (now famously) was only 14 when she was cast (having lied about her age), and had just turned 15 when the show premiered in August of 1998, but Prepon had already turned 18 in March of that year. Wilmer Valderrama was also 18, Topher Grace and Ashton Kutcher were 20, and Danny Masterson was 22.
Clint Howard was eight when he starred in Gentle Ben from 67-69.
Now, I don’t know if one would consider his adult acting career a ‘success’, but his Wiki page lists a boatload of movie credits and another boatload of TV series credits. He’s appeared in 17 movies directed by his big brother Ron.
If Danny Bonaduce is considered a success then I think Jay North would qualify for this list too. Actually though, I don’t consider either to be successful after the roles they became known for.
doh! And it was right in the OP if I had read it carefully! Hmm, what about a classic from my childhood, Silver Spoons? Ricky Schroeder, Jason Bateman, and Alfonso Ribeiro starred.
Elinor Donahue was still only 17 when Father Knows Best began. Only about 6 months from her 18th birthday so very close to the line.
To the extent that Bonaduce has had a successful career as an adult, it’s been as a radio and TV personality (radio host, TV talk show host, reality-TV star), rather than as an actor.
It’s still early for Modern Family but
Ariel Winter 1998
Rico Rodriguez 1998 are already getting roles.
Modern Family premiered September 23, 2009
Ariel is doing really well. Especially since Covid slowed everyone down in 2020.

It’ll be a few more years before their post sitcom careers can be judged.
Tuesday Weld was 16 when she first appeared on The Many Loves of Dobie Gillis.
Seth Rogan was born in 1982 and the show was in 1999, so he was definitely a minor.
Growing Pains.
Although I’m loathe to consider Kirk Cameron as successful, the show also had a young Leonardo DiCaprio (towards the end of the series, at least).
Blossom had Mayim Bialik, Joey Lawrence & Jenna von Oy, all 3 had adult success.
I would not consider Danny successful as an actor.
Oh, glad to be wrong, he might be one of the biggest successes then.
