I am not an expert but a half-sibling typically ranges from 1160-2436 and a full sibling can range from 1613-3488 according to DNA Painter which is a great tool to use when trying to guess relationships based on cm. So it seems like it is possible. I thought my half-uncle was my first cousin for a long time since both of those relationships share the same cm! This is why getting as much info as you can and getting a parent or both to test can help.
Kent, I've never once run across that. A person inherits roughly 50% (or 3400 cMs) of their DNA from each parent. This has been going on for generations and the random spin of recombination means that a full sibling doesn't inherit exactly the same segments from each parent (if they did, they'd be twins). So full siblings share on avg 2500 cMs. Half sibling are more in the range of 1200-1700 cMs.
What are the centimorgans you share with your half siblings?
Great question that I didn’t cover in the video. My half-siblings range from 1,260 to 1,687 cm!
Is it ever possible to share more CM with your half siblings than your full siblings?

Apparently Ancestry underestimates the amount of Spanish someone has. So in reality you might have more.
What proof do have of this?
^^
@@280z318i it’s true on ancestry I’m 10 percent Spaniard and my father is 36 percent and on 23andMe I’m 23 percent Spaniard and my dad is 48 percent
