That's not my diagram. I'm simply reposting a tree of life diagram that was promoted by Evolutionists back in the 1960's.
To get to Mammals on that diagram, you must first go through "Fishes."
You've identified no other Evolutionary path to the contrary, by the way (nor can you).
It's roughly accurate but insufficiently detailed, leaving out many groups, as I'm sure you ought to recognize but apparently don't.

Apparently you don't understand forks.
I'll try to explain again. Fish evolved. Fish split into several groups. One group of fish split into two other groups. One of these groups split off the tetrapods. The other group, which is not in line with the tetrapods, produced the ray-finned fish whose genes this man is talking about.
If you want to have a better chance at finding out the genetics of the tetrapodian fish ancestor, you'll need to look at the lobe-finned fishes, as I already explained in a prior post. Again, as I already explained, we share genetic features with the lobe-finned fishes that are not present in the more derived ray-finned fishes (which, again, we are not descended from).
Therefore (once more) your objection is irrelevant.
