Pakistan really should not be afraid, and even though they are not in their best form right now, I believe they are not going to lose against Netherlands. But the Netherlands should try their darnedest to win, at least one match.
In addition, New Zealand is going to be heavily favored in the match between West Indies and New Zealand. I believe that West Indies will be able to win one match. West Indies generally do well in T20 matches. So they should be able to win at least one. Especially when it is going to be played in the West Indies.
Given the recent form of Netherlands, and the unavailability of key players due to the ongoing championship, I guess they have less than 1% chance of getting any points from the ODI series. My focus is towards the New Zealand vs West Indies series. If West Indies gets some points here, then it gets tough for South Africa to gain automatic qualification for the next world cup. Here is my take on the situation as of now:
Teams that have secured qualification to 2023 CWC: Total 7 teams: England, Bangladesh, Afghanistan, New Zealand, Pakistan, West Indies, India and Australia.
One more team will qualify based on the points table, and a total of 4 teams are fighting for this spot: West Indies (most probable), Sri Lanka, Ireland and South Africa.
Zimbabwe and Netherlands have almost zero chances to qualify directly.
