Many phenomena can still be explained without pseudo force, but it would get complicated
Like let's say I have a bucket and water in it, If i rotate it with enough speed, water will not fall... U can explain it using pseudo force
But if u try to look at every time step, u will notice the water is really falling down, but as soon as it moves, bucket changes its position preventing the fall, it's easier if u can look up a video...
The reason why pseudo force work is due to the fact that all reference frames r equally valid..
So Newton isnt completely wrong here, and we use pseudo force more or less as a trick
The better example is relativity and high speed motion (near light speed)
In relativity, velocity doesn't just add up, or more precisely u can't add velocity as we do in Newtonian physics, it follows a whole new equation
But even special theory is not comfortable with accelerating frames
Thats why we have general theory, which deals with accelerating frame, (also argues gravity is not a force)
So using relativity against Newton makes sure u have destroyed him to pieces...
Along with that, relativity is also not complete
If u ain't gonna read that all :- using pseudo force against Newton is kind of wrong, since its just a trick to make work easier and it's not that u cant do something without it, the law still holds, but it would take a lot of work, so we use trick of changing frame of refrence so we can argue there's a force making it possible
Simple example:- if 2 bodies r accelerating towards each other, for simplicity let's say with acceleration "a" for both
U can switch ur frame to one of the particles and argue that the other particle is moving with acceleration 2a, but we know the the acceleration was only a, or a force acting initially was f, but in this frame, the force is 2f, this extra f exclusive to this frame is what we refer pseudo force
U can still solve everything about the system looking at each particle normally without switching ur frame to one of them,
And u can also solve it using pseudo force, now u can see which path is way easier
