No is the simple answer. It's like education and certificates, everybody will encourage you do it but won't be around to give you a job.

All the 'Yes's reflect survivor ship bias. (ask them to access you once you learn some basics which should not be difficult, if they are willing to put their money where their mouth is)

Of the more nuanced answer is - it depends. ( not elaborating on that because it often will not be useful advise).

And finally the only way to really find out is to plunge in - you will know in 5 years where you stand, you will be either doing well or really miserable.
