It is very much true

From the link you provided:

This may come as a surprise to some: it is only after two years of continued service that employees have the right to request written reasons for their dismissal.

Employers don't need to provide a reason for your dismissal.

There are some exceptions but they're very specific and unlikely to relevant. If an employer wants rid of you they can do so at their whim.

Even if you think you have a case, good luck finding a solicitor who will take on your case. They simply won't be interested because it's not easy to win without the rights you get after 2 years employment.
