Can someone please explain the protections on the 2nd pick (I think?) we have in 1st round next year?

Take as much time and as many words as you need. Explain it to me like I’m dumb (which apparently I am). Here’s how it’s spelled out on something called Fanspo.com:

OKC has the right to swap its 2025 1st round pick for HOU's 2025 1st round pick protected for selections 1-10 or the LAC' 2025 1st round pick; HOU then has the right to swap its pick or the OKC pick to BKN for PHX's 2025 1st round pick; if the HOU pick falls within its protected range, then HOU's obligation to OKC will be extinguished and HOU will instead have the right to swap its pick to BKN for the PHX pick [LAC-OKC, 7/10/2019; HOU-OKC, 7/16/2019; BKN-CLE-HOU-IND, 1/16/2021; BKN-IND-MIL-PHX, 2/9/2023; BKN-HOU, 6/26/2024]

Obviously, with this many protections it is bound to be a late first round pick. I guess my question is: Is there a scenario here where we don’t get a pick at all? And if so, how likely would you say that is?
