How to display data from http response in LWC datatable?

Apex class:

global with sharing class GetAllBetsIntegrationDemo {
	private static final String ENDPOINT_BASE = 'https://avenga-school.herokuapp.com/retrieve-data';
    private static final String GET_METHOD = 'GET';
    private static final String POST_METHOD = 'POST';    
    @AuraEnabled
    public static List<Object> getBets() {
        String endpoint = ENDPOINT_BASE;
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        request.setEndpoint(endpoint);
        request.setMethod(GET_METHOD);
        request.setHeader('Content-Type', 'application/json');
        request.setHeader('projectName', 'Totalizator');
        HttpResponse response = http.send(request);
        List<Object> responseBet = (List<Object>) JSON.deserializeUntyped(response.getBody());
        return responseBet;
    }
}

JavaScript:

import { LightningElement, wire } from 'lwc';
import getBets from '@salesforce/apex/GetAllBetsIntegrationDemo.getBets';
export default class GetBetsFromExternalApp extends LightningElement {
    columns = [
        {label: 'Player Name', fieldName: 'playerName', type: 'text'},
        {label: 'Amount', fieldName: 'amount', type: 'number'},
        {label: 'Win Rate', fieldName: 'winRate', type: 'number'},
        {label: 'Lot', fieldName: 'lot', type: 'number'},
        {label: 'Status', fieldName: 'status', type: 'text'}
    ];
    @wire(getBets) bets;
}

HTML:

<template>
    <lightning-datatable if:true={bets.data} 
        key-field="id"
        data={bets.data}
        columns={columns}
        hide-checkbox-column=true>
    </lightning-datatable>
</template>

JSON return:

{
        "amount": 1954,
        "winRate": 9,
        "lot": 4,
        "gameName": "Super Game 1",
        "playerName": "John",
        "status": "Won"
    },
    {
        "amount": 1954,
        "winRate": 4,
        "lot": 3,
        "gameName": "Super Game 2",
        "playerName": "Tom",
        "status": "Won"
    }
